* Add warning for builds with Go 1.20, so it's less surprising to users

Ideally I'd just remove the parameter to caddy.Context.Logger(), but
this would break most Caddy plugins.
Instead, I'm making it variadic and marking it as partially deprecated.
In the future, I might completely remove the parameter once most
plugins have updated.
* caddyhttp: Support sending HTTP 103 Early Hints
This adds support for early hints in the static_response handler.
* caddyhttp: Don't record 1xx responses
* push: Implement HTTP/2 server push (close#3551)

This will allow us to add more fields to customize headers in
push-specific ways in the future.
* push: Ensure Link resources are pushed before response is written
* Change header name from X-Caddy-Push to Caddy-Push
