Includes several breaking changes; code base updated accordingly.
- Added lots of context arguments
- Use fs.ErrNotExist
- Rename ACMEManager -> ACMEIssuer; CertificateManager -> Manager
* 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

* 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!

If `tls <email>` is used, we should apply that to all applicable default issuers, not drop them. This refactoring applies implicit ACME issuer settings from the tls directive to all default ACME issuers, like ZeroSSL.
We also consolidate some annoying logic and improve config validity checks.

Allows user to disable OCSP stapling (including support in the Caddyfile via the ocsp_stapling global option) or overriding responder URLs. Useful in environments where responders are not reachable due to firewalls.
* caddytls: Support multiple issuers
Defaults are Let's Encrypt and ZeroSSL.
There are probably bugs.
* Commit updated integration tests, d'oh
* Update go.mod
- Create two default automation policies; if the TLS app is used in
isolation with the 'automate' certificate loader, it will now use
an internal issuer for internal-only names, and an ACME issuer for
all other names by default.
- If the HTTP Caddyfile adds an 'automate' loader, it now also adds an
automation policy for any names in that loader that do not qualify
for public certificates so that they will be issued internally. (It
might be nice if this wasn't necessary, but the alternative is to
either make auto-HTTPS logic way more complex by scanning the names in
the 'automate' loader, or to have an automation policy without an
issuer switch between default issuer based on the name being issued
a certificate - I think I like the latter option better, right now we
do something kind of like that but at a level above each individual
automation policies, we do that switch only when no automation
policies match, rather than when a policy without an issuer does
match.)
- Set the default LoggerName rather than a LoggerNames with an empty
host value, which is now taken literally rather than as a catch-all.
- hostsFromKeys, the function that gets a list of hosts from server
block keys, no longer returns an empty string in its resulting slice,
ever.
* tls: Support placeholders in key_type
* caddytls: Simplify placeholder support for ap.KeyType

The comments in the code should explain the new logic thoroughly.
The basic problem for the issue was that we were overriding a catch-all
automation policy's explicitly-configured issuer with our own, for names
that we thought looked like public names. In other words, one could
configure an internal issuer for all names, but then our auto HTTPS
would create a new policy for public-looking names that uses the
default ACME issuer, because we assume public<==>ACME and
nonpublic<==>Internal, but that is not always the case. The new logic
still assumes nonpublic<==>Internal (on catch-all policies only), but
no longer assumes that public-looking names always use an ACME issuer.
Also fix a bug where HTTPPort and HTTPSPort from the HTTP app weren't
being carried through to ACME issuers properly. It required a bit of
refactoring.
