reverseproxy: Response buffering & configurable buffer size
Proxy response bodies can now be buffered, and the size of the request body and
response body buffer can be limited. Any remaining content that doesn't fit in the
buffer will remain on the wire until it can be read; i.e. bodies are not truncated,
even if the buffer is not big enough.

This fulfills a customer requirement. This was made possible by their sponsorship!

httpcaddyfile: Add resolvers subdir of tls (close #4008)
Allows conveniently setting the resolvers for the DNS challenge using a TLS subdirective, which applies to default issuers, rather than having to explicitly define the issuers and overwrite the defaults.

acmeserver: Support custom CAs from Caddyfile

httpcaddyfile: Fix default issuers when email provided
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.

* caddyhttp: Implement handler abort; new 'abort' directive (close #3871)

* Move abort directive ordering; clean up redirects

Seems logical for the end-all of handlers to go at the... end.

The Connection header no longer needs to be set there, since Close is
true, and the static_response handler now does that.

admin: Identity management, remote admin, config loaders (#3994)
This commits dds 3 separate, but very related features:

1. Automated server identity management

How do you know you're connecting to the server you think you are? How do you know the server connecting to you is the server instance you think it is? Mutually-authenticated TLS (mTLS) answers both of these questions. Using TLS to authenticate requires a public/private key pair (and the peer must trust the certificate you present to it).

Fortunately, Caddy is really good at managing certificates by now. We tap into that power to make it possible for Caddy to obtain and renew its own identity credentials, or in other words, a certificate that can be used for both server verification when clients connect to it, and client verification when it connects to other servers. Its associated private key is essentially its identity, and TLS takes care of possession proofs.

This configuration is simply a list of identifiers and an optional list of custom certificate issuers. Identifiers are things like IP addresses or DNS names that can be used to access the Caddy instance. The default issuers are ZeroSSL and Let's Encrypt, but these are public CAs, so they won't issue certs for private identifiers. Caddy will simply manage credentials for these, which other parts of Caddy can use, for example: remote administration or dynamic config loading (described below).

2. Remote administration over secure connection

This feature adds generic remote admin functionality that is safe to expose on a public interface.

- The "remote" (or "secure") endpoint is optional. It does not affect the standard/local/plaintext endpoint.
- It's the same as the [API endpoint on localhost:2019](https://caddyserver.com/docs/api), but over TLS.
- TLS cannot be disabled on this endpoint.
- TLS mutual auth is required, and cannot be disabled.
- The server's certificate _must_ be obtained and renewed via automated means, such as ACME. It cannot be manually loaded.
- The TLS server takes care of verifying the client.
- The admin handler takes care of application-layer permissions (methods and paths that each client is allowed to use).\
- Sensible defaults are still WIP.
- Config fields subject to change/renaming.

3. Dyanmic config loading at startup

Since this feature was planned in tandem with remote admin, and depends on its changes, I am combining them into one PR.

Dynamic config loading is where you tell Caddy how to load its config, and then it loads and runs that. First, it will load the config you give it (and persist that so it can be optionally resumed later). Then, it will try pulling its _actual_ config using the module you've specified (dynamically loaded configs are _not_ persisted to storage, since resuming them doesn't make sense).

This PR comes with a standard config loader module called `caddy.config_loaders.http`.

Caddyfile config for all of this can probably be added later.

COMMITS:

* admin: Secure socket for remote management

Functional, but still WIP.

Optional secure socket for the admin endpoint is designed
for remote management, i.e. to be exposed on a public
port. It enforces TLS mutual authentication which cannot
be disabled. The default port for this is :2021. The server
certificate cannot be specified manually, it MUST be
obtained from a certificate issuer (i.e. ACME).

More polish and sensible defaults are still in development.

Also cleaned up and consolidated the code related to
quitting the process.

* Happy lint

* Implement dynamic config loading; HTTP config loader module

This allows Caddy to load a dynamic config when it starts.

Dynamically-loaded configs are intentionally not persisted to storage.

Includes an implementation of the standard config loader, HTTPLoader.
Can be used to download configs over HTTP(S).

* Refactor and cleanup; prevent recursive config pulls

Identity management is now separated from remote administration.

There is no need to enable remote administration if all you want is identity
management, but you will need to configure identity management
if you want remote administration.

* Fix lint warnings

* Rename identities->identifiers for consistency

caddycmd: Add upgrade command (#3972)
Replaces the current Caddy executable with a new one from the build server. Honors custom builds, as long as plugins are registered on the Caddy website. Requires permissions to replace current executable, of course.

caddytest: Update Caddyfile tests for formatting, HTTP-only blocks
Previous commit improved the Caddyfile adapter so it doesn't unnecessarily add names to "skip" in "auto_https" when the server is already HTTP-only.

This commit updates the tests to reflect that change, while also fixing the Caddyfile formatting in many of the tests.

We also print the line number of the divergence between input and formatted version in Caddyfile adapt warnings - very useful for finding initial formatting problems.

httpcaddyfile: Support repeated use of cert_issuer global option
This changes the signature of UnmarshalGlobalFunc but this is probably OK since it's only used by this repo as far as we know.

We need this change in order to "remember" the previous value in case a global option appears more than once, which is now a possibility with the cert_issuer option since Caddy now supports multiple issuers in the order defined by the user.

Bonus: the issuer subdirective of tls now supports one-liner for "acme" when all you need to set is the directory:

issuer acme <dir>
