Allow full-gc to prune both local and remote snapshots

[golyalpha]

Currently setting the schedule to full-gc only cleans up the local storage, and ignores remotes and any retention policies set there. This is a problem because that means the only way to cleanup remote snapshots is either with an admin manually running the remote-prune command, or and external tool (be it a mod, or rcon + crontab).

Ideally, a new scheduling option (for example full-gc-remote) would exist that would make the schedule run a full backup, local prune and gc followed by remote prune.

Alternatively a schedule-remote-prune configuration option could be provided, which if enabled, would cause the standard full-gc action to perform the remote prune when triggered.

Unfortunately, this isn't really possible - git itself has no way to perform those actions on a remote. You have to run those commands on whatever is hosting the remote repo.

I understand that a client cannot garbage collect a remote - that's not really what I'm asking for however.

I'm asking for a way to schedule a remote prune, which currently doesn't exist, but the mod is fully capable of doing manually.

Ah I misread, conflated it with a similar issue that got filed. Yes, understood, that's entirely reasonable. Thanks.
