caddytls: Change clustering to be a plugin to the caddytls package (#2459)
* caddytls: Change clustering to be a plugin to the caddytls package

Should resolve the failure in
https://github.com/coredns/coredns/pull/2541.

This change is breaking to clustering plugin developers (not Caddy
users), but logical, since only the caddytls package uses CertMagic
directly (the httpserver package also uses it, but only because it also
uses the caddytls plugin); and it is early enough that no clustering
plugins really exist yet.

This will also require a change of devportal
so that it looks for a different registration function, which has moved
to the caddytls package.

* Remove unused variable

* caddyhttp: Fix test (adjust plugin counting)

* ummmm, remove extra line break

somehow VS Code didn't fmt on save... weird.

Extract most of caddytls core code into external CertMagic package
All code relating to a caddytls.Config and setting it up from the
Caddyfile is still intact; only the certificate management-related
code was removed into a separate package.

I don't expect this to build in CI successfully; updating dependencies
and vendor is coming next.

I've also removed the ad-hoc, half-baked storage plugins that we need
to finish making first-class Caddy plugins (they were never documented
anyway). The new certmagic package has a much better storage interface,
and we can finally move toward making a new storage plugin type, but
it shouldn't be configurable in the Caddyfile, I think, since it doesn't
make sense for a Caddy instance to use more than one storage config...

We also have the option of eliminating DNS provider plugins and just
shipping all of lego's DNS providers by using a lego package (the
caddytls/setup.go file has a comment describing how) -- but it doubles
Caddy's binary size by 100% from about 19 MB to around 40 MB...!

httpserver: Raise error when adjusted site addresses clash at startup
See discussion on #2015 for how this situation was discovered. For a
Caddyfile like this:

	localhost {
		...
	}
	:2015 {
		...
	}

Running Caddy like this:

	caddy -host localhost

Produces two sites both defined as `localhost:2015` because the flag
changes the default host value to be `localhost`. This should be an
error since the sites are not distinct and it is confusing. It can also
cause issues with TLS handshakes loading the wrong cert, as the linked
discussion shows.

tls: Synchronize renewals between Caddy instances sharing file storage
Also introduce caddy.OnProcessExit which is a list of functions that
run before exiting the process cleanly; these do not count as shutdown
callbacks, so they do not return errors and must execute quickly.

tls: Restructure and improve certificate management
- Expose the list of Caddy instances through caddy.Instances()

- Added arbitrary storage to caddy.Instance

- The cache of loaded certificates is no longer global; now scoped
  per-instance, meaning upon reload (like SIGUSR1) the old cert cache
  will be discarded entirely, whereas before, aggressively reloading
  config that added and removed lots of sites would cause unnecessary
  build-up in the cache over time.

- Key certificates in the cache by their SHA-256 hash instead of
  by their names. This means certificates will not be duplicated in
  memory (within each instance), making Caddy much more memory-efficient
  for large-scale deployments with thousands of sites sharing certs.

- Perform name-to-certificate lookups scoped per caddytls.Config instead
  of a single global lookup. This prevents certificates from stepping on
  each other when they overlap in their names.

- Do not allow TLS configurations keyed by the same hostname to be
  different; this now throws an error.

- Updated relevant tests, with a stark awareness that more tests are
  needed.

- Change the NewContext function signature to include an *Instance.

- Strongly recommend (basically require) use of caddytls.NewConfig()
  to create a new *caddytls.Config, to ensure pointers to the instance
  certificate cache are initialized properly.

- Update the TLS-SNI challenge solver (even though TLS-SNI is disabled
  currently on the CA side). Store temporary challenge cert in instance
  cache, but do so directly by the ACME challenge name, not the hash.
  Modified the getCertificate function to check the cache directly for
  a name match if one isn't found otherwise. This will allow any
  caddytls.Config to be able to help solve a TLS-SNI challenge, with one
  extra side-effect that might actually be kind of interesting (and
  useless): clients could send a certificate's hash as the SNI and
  Caddy would be able to serve that certificate for the handshake.

- Do not attempt to match a "default" (random) certificate when SNI
  is present but unrecognized; return no certificate so a TLS alert
  happens instead.

- Store an Instance in the list of instances even while the instance
  is still starting up (this allows access to the cert cache for
  performing renewals at startup, etc). Will be removed from list again
  if instance startup fails.

- Laid groundwork for ACMEv2 and Let's Encrypt wildcard support.

Server type plugins will need to be updated slightly to accommodate
minor adjustments to their API (like passing in an Instance). This
commit includes the changes for the HTTP server.

Certain Caddyfile configurations might error out with this change, if
they configured different TLS settings for the same hostname.

This change trades some complexity for other complexity, but ultimately
this new complexity is more correct and robust than earlier logic.

0a0d2cc1cf Use RequestURI when redirecting to canonical path. (#1331)
* Use RequestURI when redirecting to canonical path.

Caddy may trim a request's URL path when it starts with the path that's
associated with the virtual host. This change uses the path from the request's
RequestURI when performing a redirect.

Fix issue #1327.

* Rename redirurl to redirURL.

* Redirect to the full URL.

The scheme and host from the virtual host's site configuration is used
in order to redirect to the full URL.

* Add comment and remove redundant check.

* Store the original URL path in request context.

By storing the original URL path as a value in the request context,
middlewares can access both it and the sanitized path. The default
default FileServer handler will use the original URL on redirects.

* Replace contextKey type with CtxKey.

In addition to moving the CtxKey definition to the caddy package, this
change updates the CtxKey references in the httpserver, fastcgi, and
basicauth packages.

* httpserver: Fix reference to CtxKey

82cbd7a96b Detect HTTPS interception (#1430)
* WIP: Implement HTTPS interception detection by Durumeric, et. al.

Special thanks to @FiloSottile for guidance with the custom listener.

* Add {{.IsMITM}} context action and {mitm} placeholder

* Improve MITM detection heuristics for Firefox and Edge

* Add tests for MITM detection heuristics

* Improve Safari heuristics for interception detection

* Read ClientHello during first Read() instead of during Accept()

As far as I can tell, reading the ClientHello during Accept() prevents
new connections from being accepted during the read. Since Read() should
be called in its own goroutine, this keeps Accept() non-blocking.

* Clean up MITM detection handler; make possible to close connection

* Use standard lib cipher suite values when possible

* Improve Edge heuristics and test cases

* Refactor MITM checking logic; add some debug statements for now

* Fix bug in MITM heuristic tests and actual heuristic code

* Fix gofmt

* Remove debug statements; preparing for merge
