notify: Send all sd_notify signals from main caddy process (#4060)
Initial sd_notify support was added in #3963, but that sent signals from
both cmdRun and cmdReload.  This approach has two drawbacks:

- Reloads initiated via the API do not send signals.
- The signals are sent from different processes, which requires the
  `NotifyAccess=exec` directive in the unit file.

This change moves the NotifyReloading and NotifyReadiness invocations to
Load, which address both of those drawbacks.  It also adds a
complimentary NotifyStopping method which is invoked from handleStop.
All the notify methods are defined in a notify package to avoid an
import loop.

Change os to ioutil for now
My editor automatically changed ioutil.ReadFile() to os.ReadFile() in accordance
with Go 1.16 changes. I didn't notice this until pushing.

But we still have to support Go 1.15 for a little while.

caddy: Add InstanceID() method
Caddy can now generate and persist its own instance ID, a UUID that is stored in
the data directory.

This makes it possible to differentiate it from other instances in a cluster.

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

b8cba62643 Refactor for CertMagic v0.10; prepare for PKI app
This is a breaking change primarily in two areas:
 - Storage paths for certificates have changed
 - Slight changes to JSON config parameters

Huge improvements in this commit, to be detailed more in
the release notes.

The upcoming PKI app will be powered by Smallstep libraries.

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.

core: Major refactor of admin endpoint and config handling
Fixed several bugs and made other improvements. All config changes are
now mediated by the global config state manager. It used to be that
initial configs given at startup weren't tracked, so you could start
caddy with --config caddy.json and then do a GET /config/ and it would
return null. That is fixed, along with several other general flow/API
enhancements, with more to come.

Clean up provisioned modules on error; refactor Run(); add Validate()
Modules that return an error during provisioning should still be cleaned
up so that they don't leak any resources they may have allocated before
the error occurred. Cleanup should be able to run even if Provision does
not complete fully.
