* reverseproxy: New `copy_response` handler for `handle_response` routes
Followup to #4298 and #4388.
This adds a new `copy_response` handler which may only be used in `reverse_proxy`'s `handle_response` routes, which can be used to actually copy the proxy response downstream.
Previously, if `handle_response` was used (with routes, not the status code mode), it was impossible to use the upstream's response body at all, because we would always close the body, expecting the routes to write a new body from scratch.
To implement this, I had to refactor `h.reverseProxy()` to move all the code that came after the `HandleResponse` loop into a new function. This new function `h.finalizeResponse()` takes care of preparing the response by removing extra headers, dealing with trailers, then copying the headers and body downstream.
Since basically what we want `copy_response` to do is invoke `h.finalizeResponse()` at a configurable point in time, we need to pass down the proxy handler, the response, and some other state via a new `req.WithContext(ctx)`. Wrapping a new context is pretty much the only way we have to jump a few layers in the HTTP middleware chain and let a handler pick up this information. Feels a bit dirty, but it works.
Also fixed a bug with the `http.reverse_proxy.upstream.duration` placeholder, it always had the same duration as `http.reverse_proxy.upstream.latency`, but the former was meant to be the time taken for the roundtrip _plus_ copying/writing the response.
* Delete the "Content-Length" header if we aren't copying
Fixes a bug where the Content-Length will mismatch the actual bytes written if we skipped copying the response, so we get a message like this when using curl:
```
curl: (18) transfer closed with 18 bytes remaining to read
```
To replicate:
```
{
admin off
debug
}
:8881 {
reverse_proxy 127.0.0.1:8882 {
@200 status 200
handle_response @200 {
header Foo bar
}
}
}
:8882 {
header Content-Type application/json
respond `{"hello": "world"}` 200
}
```

* Add a override_domain option to allow DNS chanllenge delegation
CNAME can be used to delegate answering the chanllenge to another DNS
zone. One usage is to reduce the exposure of the DNS credential [1].
Based on the discussion in caddy/certmagic#160, we are adding an option
to allow the user explicitly specify the domain to delegate, instead of
following the CNAME chain.
This needs caddy/certmagic#160.

The `net.JoinHostPort()` function has some naiive logic for handling IPv6, it just checks if the host part has a `:` and if so it wraps the host part with `[ ]` but this causes our network type prefix to get wrapped as well, which is invalid for `caddy.NetworkAddress`. Instead, we can just concatenate the host and port manually here to avoid this side-effect.
We realized we made some mistakes with the directive ordering, so we're making some minor adjustments.
`abort` and `error` don't really make sense to be after other handler directives, because you would expect to be able to "fail-fast" and throw an error before falling through to some `file_server` or `respond` typically. So we're moving them up to just before `respond`, i.e. before the common handler directives.
This is also more consistent with our existing examples in the docs, which actually didn't work due to the directive ordering. See https://caddyserver.com/docs/caddyfile/directives/error#examples
Also, `push` doesn't quite make sense to be after `handle`/`route`, since its job is to read from response headers to push additional resources if necessary, and `handle`/`route` may be terminal so push would not be reached if it was declared outside those. And also, it would make sense to be _before_ `templates` because a template _could_ add a `Link` header to the response dynamically.
Some new users mistakenly try to define two sites without braces around each. Doing this can yield a confusing error message saying that their site address is an "unknown directive".
We can do better by keeping track of whether the current site block was parsed with or without a brace, then changing the error message later based on that.
For example, now this invalid config:
```
foo.example.com
respond "foo"
bar.example.com
respond "bar"
```
Will yield this error message:
```
$ caddy adapt
2021/08/22 19:21:31.028 INFO using adjacent Caddyfile
adapt: Caddyfile:4: unrecognized directive: bar.example.com
Did you mean to define a second site? If so, you must use curly braces around each site to separate their configurations.
```
* httpcaddyfile: Add shortcut for proxy hostport placeholder
I've noticed that it's a pretty common pattern to write a proxy like this, when needing to proxy over HTTPS:
```
reverse_proxy https://example.com {
header_up Host {http.reverse_proxy.upstream.hostport}
}
```
I find it pretty hard to remember the exact placeholder to use for this, and I continually need to refer to the docs when I need it. I think a simple fix for this is to add another Caddyfile placeholder for this one to shorten it:
```
reverse_proxy https://example.com {
header_up Host {proxy_hostport}
}
```
* Switch the shortcut name
* httpcaddyfile: ensure hosts to skip can always be collected
Previously, some hosts that should be skipped in logging would
be missed as the current logic would only collect them after
encountering the first server that would log. This change makes sure
the ServerLogConfig is initialized before iterating over the server
blocks.
* httpcaddyfile: add test case for skip hosts behavior
If an email is specified in global options, a site called 'localhost' shouldn't be bunched together with public DNS names in the automation policies, which get the default, public-CA issuers. Fix old test that did this.
I also noticed that these two:
localhost {
}
example.com {
}
and
localhost, example.com {
}
produce slightly different TLS automation policies. The former is what the new test case covers, and we have logic that removes the empty automation policy for localhost so that auto-HTTPS can implicitly create one. (We prefer that whenever possible.) But the latter case produces two automation policies, with the second one being for localhost, with an explicit internal issuer. It's not wrong, just more explicit than it needs to be.
I'd really like to completely rewrite the code from scratch that generates automation policies, hopefully there is a simpler, more correct algorithm.
In the Caddyfile, hosts specified for HTTP sockets (either scheme is "http" or it is on the HTTP port) should not be used as subjects in TLS automation policies (APs).

This change is aimed at enhancing the logging module within the
Caddyfile directive to allow users to configure logs other than the HTTP
access log stream, which is the current capability of the Caddyfile [1].
The intent here is to leverage the same syntax as the server log
directive at a global level, so that similar customizations can be added
without needing to resort to a JSON-based configuration.
Discussion for this approach happened in the referenced issue.
Closes https://github.com/caddyserver/caddy/issues/3958
[1] https://caddyserver.com/docs/caddyfile/directives/log
Allows conveniently setting the resolvers for the DNS challenge using a TLS subdirective, which applies to default issuers, rather than having to explicitly define the issuers and overwrite the defaults.
The HTTP Caddyfile adapter can now configure the PKI app, and the acme_server directive can now be used to specify a custom CA used for issuing certificates. More customization options can follow later as needed.
If `tls <email>` is used, we should apply that to all applicable default issuers, not drop them. This refactoring applies implicit ACME issuer settings from the tls directive to all default ACME issuers, like ZeroSSL.
We also consolidate some annoying logic and improve config validity checks.

* caddyhttp: Implement handler abort; new 'abort' directive (close#3871)
* Move abort directive ordering; clean up redirects
Seems logical for the end-all of handlers to go at the... end.
The Connection header no longer needs to be set there, since Close is
true, and the static_response handler now does that.
This is probably an invasive change, but existing tests continue to pass.
It seems to make sense this way. There is likely an edge case I haven't
considered.
Allows user to disable OCSP stapling (including support in the Caddyfile via the ocsp_stapling global option) or overriding responder URLs. Useful in environments where responders are not reachable due to firewalls.
This changes the signature of UnmarshalGlobalFunc but this is probably OK since it's only used by this repo as far as we know.
We need this change in order to "remember" the previous value in case a global option appears more than once, which is now a possibility with the cert_issuer option since Caddy now supports multiple issuers in the order defined by the user.
Bonus: the issuer subdirective of tls now supports one-liner for "acme" when all you need to set is the directory:
issuer acme <dir>

* implement default values for header directive
closes#3804
* remove `set_default` header op and rely on "require" handler instead
This has the following advantages over the previous attempt:
- It does not introduce a new operation for headers, but rather nicely
extends over an existing feature in the header handler.
- It removes the need to specify the header as "deferred" because it is
already implicitely deferred by the use of the require handler. This
should be less confusing to the user.

* httpcaddyfile: Revise automation policy generation
This should fix a frustrating edge case where wildcard subjects are

by an actual customer requirement.
Although all the tests pass, this logic is incredibly complex and
nuanced, and I'm worried it is not correct. But it took me about 4 days
to get this far on a solution. I did my best.
* Fix typo
We have users that have site blocks like *.*.tld with on-demand TLS
enabled. While *.*.tld does not qualify for a publicly-trusted cert due
to its wildcards, On-Demand TLS does not actually obtain a cert with
those wildcards, since it uses the actual hostname on the handshake.
This improves on that logic, but I am still not 100% satisfied with the
result since I think we need to also check if another site block is more
specific, like foo.example.tld, which might not have on-demand TLS
enabled, and make sure an automation policy gets created before the
more general policy with on-demand...

We recently introduced `if !cp.SettingsEmpty()` which conditionally
adds the connection policy to the list. If the condition evaluates to
false, the policy wouldn't actually be added, even if
hasCatchAllTLSConnPolicy was set to true on the previous line.
Now we set that variable in accordance with whether we actually add
the policy.
While debugging this I noticed that catch-all policies added early in
that loop (i.e. not at the end if we later determine we need one) are
not always at the end of the list. They should be, though, since they
are selected by which one matches first, and having a catch-all first
would nullify any more specific ones later in the list. So I added a
sort in consolidateConnPolicies to take care of that.
Should fix#3670 and
https://caddy.community/t/combining-on-demand-tls-with-custom-ssl-certs-doesnt-seem-to-work-in-2-1-1/9719
but I won't know for sure until somebody verifies it, since at least in
the GitHub issue there is not yet enough information (the configs are
redacted).

* caddytls: Add support for ZeroSSL; add Caddyfile support for issuers
Configuring issuers explicitly in a Caddyfile is not easily compatible
with existing ACME-specific parameters such as email or acme_ca which
infer the kind of issuer it creates (this is complicated now because
the ZeroSSL issuer wraps the ACME issuer)... oh well, we can revisit
that later if we need to.
New Caddyfile global option:
{
cert_issuer <name> ...
}
Or, alternatively, as a tls subdirective:
tls {
issuer <name> ...
}
For example, to use ZeroSSL with an API key:
{
cert_issuser zerossl API_KEY
}
For now, that still uses ZeroSSL's ACME endpoint; it fetches EAB
credentials for you. You can also provide the EAB credentials directly
just like any other ACME endpoint:
{
cert_issuer acme {
eab KEY_ID MAC_KEY
}
}
All these examples use the new global option (or tls subdirective). You
can still use traditional/existing options with ZeroSSL, since it's
just another ACME endpoint:
{
acme_ca https://acme.zerossl.com/v2/DV90
acme_eab KEY_ID MAC_KEY
}
That's all there is to it. You just can't mix-and-match acme_* options
with cert_issuer, because it becomes confusing/ambiguous/complicated to
merge the settings.

Catch-alls should always go last. Normally this is the case, but we have
a special case for comparing one wildcard-host site block to another
non-wildcard host site block; and a catch-all site block is also a
non-wildcard host site block, so now we have to special-case the
catch-all site block. Sigh.
This could be reproduced with a Caddyfile that has two site blocks:
":80" and "*.example.com", in that order.

This removes an optimization where we amortized path matcher decoding.
The decoded matchers were index by... position... which obviously
changes during sorting. Duh.
Anyway, sorting is sliiightly slower now but the Caddyfile is not
really CPU-sensitive, so this is fine.
This can lead to nicer, smaller JSON output for Caddyfiles like this:
a {
tls internal
}
b {
tls foo@bar.com
}
i.e. where the tls directive only configures automation policies, and
is merely meant to enable TLS on a server block (if it wasn't implied).
This helps keeps implicit config implicit.
Needs a little more testing to ensure it doesn't break anything
important.
