This migrates a feature that was previously reserved for enterprise
users, according to https://github.com/caddyserver/caddy/issues/2786.
The PEM loader allows you to embed PEM files (certificates and keys)
directly into your config, rather than requiring them to be stored on
potentially insecure storage, which adds attack vectors. This is useful
in automated settings where sensitive key material is stored only in
memory.
Note that if the config is persisted to disk, that added benefit may go
away, but there will still be the benefit of having lesser dependence on
external files.
Making them pointers makes for cleaner JSON when adapting configs, if
the struct is empty now it will be omitted entirely.
The x/time/rate package was updated to support changing the burst, so
we've incorporated that here and removed a TODO.

Use piles from which to draw config values.
Module values can return their name, so now we can do two-way mapping
from value to name and name to value; whereas before we could only map
name to value. This was problematic with the Caddyfile adapter since
it receives values and needs to know the name to put in the config.
Along with several other changes, such as renaming caddyhttp.ServerRoute
to caddyhttp.Route, exporting some types that were not exported before,
and tweaking the caddytls TLS values to be more consistent.
Notably, we also now disable automatic cert management for names which
already have a cert (manually) loaded into the cache. These names no
longer need to be specified in the "skip_certificates" field of the
automatic HTTPS config, because they will be skipped automatically.
