[feature] Make log format configurable (#2130)
* [feature] Don't emit timestamp in log lines

When running gotosocial with a service manager like systemd, or a
container runtime, the associated log driver usually emits timestamps
itself. In those cases, having the extra timestamp from our own log
lines ends up being a bit noisy and when centrally ingesting logs is
duplicate information.

This introduces a configuration flag that allows disabling emitting the
timestamp. It's only wired up for "daemonised" processes, meaning server
and testrig.

* [feature] Simplify timestamp handling

Daenney da8282081c
[feature] Lower remote media cache config duration (#2007)
The old default of 30d can lead to a lot of media getting cached and
significant disk usage, even on small or single person instances. A lot
of deployments decrease this value, to 15 or even less. This is less of
an issue when using object storage, but for local storage which is the
more popular deployment option running out of disk space is unpleasant.

With GoToSocial's aim to fit in small places, this changes the default
to a much more conservative 7 days. In all likelihood people aren't
scrolling that far back in their timeline so this change shouldn't
result in any issue. Existing deployments will only be affected by
this change if the admin hasn't already configured this value, or didn't
bootstrap from the example configuration.

[feature] Allow loading TLS certs from disk (#1586)
Currently, GtS only supports using the built-in LE client directly for
TLS. However, admins may still want to use GtS directly (so without a
reverse proxy) but with certificates provided through some other
mechanism. They may have some centralised way of provisioning these
things themselves, or simply prefer to use LE but with a different
challenge like DNS-01 which is not supported by autocert.

This adds support for loading a public/private keypair from disk instead
of using LE and reconfigures the server to use a TLS listener if we
succeed in doing so.

Additionally, being able to load TLS keypair from disk opens up the path
to using a custom CA for testing purposes avoinding the need for a
constellation of containers and something like Pebble or Step CA to
provide LE APIs.

[feature] Make OIDC admin groups configurable (#1555)
This removes the current default of checking for membership of the admin
or admins group and makes it required to explicitly configure which
groups should grant admin access, if any.

Relying on the implicit default of admin or admins is potentially
dangerous as that group may contain a different subset of people that we
may wish to grant admin access to GtS. This is probably not an issue for
a single-person instance, but for a community instance different admin
groups may exist in an OIDC provider for different applications.

I'm explicitly opting for not defaulting the value of oidc-admin-groups
to admin,admins because I think it's better for those things to be
explicitly configured.

[feature] Add a request ID and include it in logs (#1476)
This adds a lightweight form of tracing to GTS. Each incoming request is
assigned a Request ID which we then pass on and log in all our log
lines. Any function that gets called downstream from an HTTP handler
should now emit a requestID=value pair whenever it logs something.
