reverseproxy: Caddyfile health check headers, host header support (#3948)
* reverse_proxy: 1.health check headers can be set through Caddyfile using health_headers directive; 2.health check header host can be set properly

* reverse_proxy:
replace example with syntax definition
inline health_headers directive parse function

* bugfix: change caddyfile_adapt testcase file from space to tab

* reverseproxy: modify health_header value document as optional and add more test cases

caddyfile: Introduce basic linting and fmt check (#3923)
* caddyfile: Introduce basic linting and fmt check

This will help encourage people to keep their Caddyfiles tidy.

* Remove unrelated tests

I am not sure that testing the output of warnings here is quite the
right idea; these tests are just for syntax and parsing success.

headers: Support default header values in Caddyfile with '?' (#3807)
* 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.

* caddyhttp: New idle_timeout default of 5m

* reverseproxy: fix random hangs on http/2 requests with server push (#3875)

see https://github.com/golang/go/issues/42534

* Refactor and cleanup with improvements

* More specific link

reverseproxy: Allow using TLS for port 80 upstreams (see #3361)
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.

260982b2df reverse_proxy: Allow use of URL to specify scheme
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: Module documentation; refactor LoadModule(); new caddy struct tags (#2924)
This commit goes a long way toward making automated documentation of
Caddy config and Caddy modules possible. It's a broad, sweeping change,
but mostly internal. It allows us to automatically generate docs for all
Caddy modules (including future third-party ones) and make them viewable
on a web page; it also doubles as godoc comments.

As such, this commit makes significant progress in migrating the docs
from our temporary wiki page toward our new website which is still under
construction.

With this change, all host modules will use ctx.LoadModule() and pass in
both the struct pointer and the field name as a string. This allows the
reflect package to read the struct tag from that field so that it can
get the necessary information like the module namespace and the inline
key.

This has the nice side-effect of unifying the code and documentation. It
also simplifies module loading, and handles several variations on field
types for raw module fields (i.e. variations on json.RawMessage, such as
arrays and maps).

I also renamed ModuleInfo.Name -> ModuleInfo.ID, to make it clear that
the ID is the "full name" which includes both the module namespace and
the name. This clarity is helpful when describing module hierarchy.

As of this change, Caddy modules are no longer an experimental design.
I think the architecture is good enough to go forward.
