[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.

* [chore] Add docs for log-timestamp

* [feature] Simplify timestamp handling
