* Add otelhttp instrumentation, update OpenTelemetry libraries.
* Use otelhttp instrumentation for instrumenting HTTP requests.
This change uses context.WithValue to inject the next handler into the
request context via a "nextCall" carrier struct, and pass it on to a
standard Go HTTP handler returned by otelhttp.NewHandler. The
underlying handler will extract the next handler from the context,
call it and pass the returned error to the carrier struct.

* 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.
* rename override_domain to dns_challenge_override_domain
* Update CertMagic; fix spelling

Huge thank-you to Tailscale (https://tailscale.com) for making this change possible!
This is a great feature for Caddy and Tailscale is a great fit for a standard implementation.
* caddytls: GetCertificate modules; Tailscale
* Caddyfile support for get_certificate
Also fix AP provisioning in case of empty subject list (persist loaded
module on struct, much like Issuers, to surive reprovisioning).
And implement start of HTTP cert getter, still WIP.
* Update modules/caddytls/automation.go
Co-authored-by: Francis Lavoie <lavofr@gmail.com>
* Use tsclient package, check status for name
* Implement HTTP cert getter
And use reuse CertMagic's PEM functions for private keys.
* Remove cache option from Tailscale getter
Tailscale does its own caching and we don't need the added complexity...
for now, at least.
* Several updates
- Option to disable cert automation in auto HTTPS
- Support multiple cert managers
- Remove cache feature from cert manager modules
- Minor improvements to auto HTTPS logging
* Run go mod tidy
* Try to get certificates from Tailscale implicitly
Only for domains ending in .ts.net.
I think this is really cool!

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.
```
|
|
Some users forget to use a comma between their site addresses. This is invalid (commas aren't a valid character in domains) and later parts of the code like certificate automation will try to use this otherwise, which doesn't make sense. Best to error as early as possible.
Example thread on the forums where this happened: https://caddy.community/t/simplify-caddyfile/13281/9

* 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
|
|
* caddyfile: Errf enable error chain unwrapping
* refactor: remove parseError

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).

* caddyfile: Add parse error on site address in `{`
This is an incredibly common mistake made by users, so we should catch it earlier in the parser and give a more friendly message. Often it ends up adapting but with mistakes, or erroring out later due to other site addresses being read as directives.
There's not really ever a situation where a lone '{' is valid at the end of a site address (but I suppose there are edgecases where the user wants to use a path matcher where it ends specifically in `{`, but... why?), so this should be fine.
* Update caddyconfig/caddyfile/parse.go
|
|
Also fix a previous test that asserted incorrect behavior.

* caddyfile(formatter): fix nesting not decrementing
This is an extremely weird edge-case where if you had a environment variable {}
on one line, a comment on the next line, and the closing of the block on the
following line; the rest of the Caddyfile would be indented further than it
should've been.
ref; https://github.com/matthewpi/vscode-caddyfile-support/issues/13
* run gofmt
* fmt: better way of handling edge case

* httpcaddyfile: Fix unexpectedly removed policy
When user set on_demand tls option in a catch-all (:443) policy,
we expect other policies to not have the on_demand enabled
See ex in tls_automation_policies_5.txt
Btw, we can remove policies if they are **all** empty.
* Update caddyconfig/httpcaddyfile/tlsapp.go

* caddyfile: Fix `import` replacing unrelated placeholders
See https://caddy.community/t/snippet-issue-works-outside-snippet/12231
So it turns out that `NewReplacer()` gives a replacer with some global defaults (like `{env.*}` and some system and time placeholders), which is not ideal when running `import` because we just want to replace `{args.*}` only, and nothing else.
* caddyfile: Add test
