* 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.
* add integration test for header directive in caddyfile
* bubble up errors when parsing caddyfile header directive
* don't export unnecessarily and don't canonicalize headers unnecessarily
* fix response headers not passed in blocks
* caddyfile: fix clash when using default header in block
Each header is now set in a separate handler so that it doesn't clash
with other headers set/added/deleted in the same block.

We already restore them within the retry loop, but after successful
proxy we didn't reset them, so as handlers bubble back up, they would
see the values used for proxying.
Thanks to @ziddey for identifying the cause.

In commit f2ce81c, support for multiple path splitters was added. The
type of SplitPath changed from string to []string, and splitPos was
changed to loop through all values in SplitPath.
Before that commit, if SplitPath was empty, strings.Index returned 0 and
PATH_INFO was set correctly in buildEnv.
Currently, however, splitPos returns -1 for empty values of SplitPath,
behaving as if a split position could not be found at all. PATH_INFO is
then never set in buildEnv and remains empty.
Restore the old behaviour by explicitly checking whether SplitPath is
empty and returning 0 in splitPos.
Closes#3490
Correct behavior is not well defined because this is a non-standard
header field. This could be a "hop-by-hop" field much like
X-Forwarded-For is, but even our X-Forwarded-For implementation
preserves prior entries. Or, it could be best to preserve the original
value from the first hop, representing the protocol as facing the
client.
Let's try it the other way for a bit and see how it goes.

An upstream like https://localhost:80 is still forbidden, but an addr of
localhost:80 can be used while explicitly enabling TLS as an override;
we just don't allow the implicit behavior to be ambiguous.

Moving to https://github.com/caddyserver/circuitbreaker
Nobody was using it anyway -- it works well, but something got fumbled
in a refactoring *months* ago. Turns out that we forgot the interface
guards AND botched a method name (my bad) - Ok() should have been OK().
So it would always have thrown a runtime panic if it tried to be loaded.
The module itself works well, but obviously nobody used it because
nobody reported the error. Fixing this while we move it to the new repo.
Removing this removes the last Bazaar/Launchpad dependency (I think).

Either Dial or LookupSRV will be set, but if we rely on Dial always
being set, we could run into bugs.
Note: Health checks don't support SRV upstreams.
Adds `Alt-Svc` to the list of headers that get removed when proxying
to a backend.
This fixes the issue of having the contents of the Alt-Svc header
duplicated when proxying to another Caddy server.

This is a breaking change primarily in two areas:
- Storage paths for certificates have changed
- Slight changes to JSON config parameters
Huge improvements in this commit, to be detailed more in
the release notes.
The upcoming PKI app will be powered by Smallstep libraries.
This makes it more convenient to configure quick proxies that use HTTPS
but also introduces a lot of logical complexity. We have to do a lot of
verification for consistency and errors.
Path and query string is not supported (i.e. no rewriting).
Scheme and port can be inferred from each other if HTTP(S)/80/443.
If omitted, defaults to HTTP.
Any explicit transport config must be consistent with the upstream
schemes, and the upstream schemes must all match too.
But, this change allows a config that used to require this:
reverse_proxy example.com:443 {
transport http {
tls
}
}
to be reduced to this:
reverse_proxy https://example.com
which is really nice syntactic sugar (and is reminiscent of Caddy 1).
* v2: add documentation for circuit breaker config and "random selection" load balancing policy
* v2: rename circuit breaker config inline key from `type` to `breaker` to avoid json key clash between the `circuit_breaker` type and the `type` field of the generic circuit breaker Config struct used by circuit breaking implementations
* v2: restore the circuit breaker inline key to `type` and rename the name circuit breaker config field from `Type` to `Factor`
The fix that was initially put forth in #2971 was good, but only for
up to one layer of nesting. The real problem was that we forgot to
increment nesting when already inside a block if we saw another open
curly brace that opens another block (dispenser.go L157-158).
The new 'handle' directive allows HTTP Caddyfiles to be designed more
like nginx location blocks if the user prefers. Inside a handle block,
directives are still ordered just like they are outside of them, but
handler blocks at a given level of nesting are mutually exclusive.
This work benefitted from some refactoring and cleanup.
