Leaderboard Updating, Leaderboard Resetting, Run Deletion

[tsa96]

murgle started working on this a while ago, but it's for the old backend and frontend code is really outdated, so not much point keeping the PR open given it'd be best to just remake it anyway. Closing that one, and getting an issue started for the feature.

I'm a little hesitant to start working on this yet, since post 0.10 leaderboard and rank XP systems will completely change how we process and store leaderboard rankings and XP. So, leaving this blocks for now, but we should work on this once we start doing rank/leaderboard changes.

We should also add an endpoint for resetting entire leaderboards. This will be very rare and should only be available to admins.

Adding even more onto this issue. Currently admins/mods can't submit MapVersions, but we definitely want this. However, if we allow zone updates in that case, we may have leaderboard updates to as well, and the logic seems very complicated.

I'd love to get this in for 0.10.0, but not sure it's worth working on right now.

Don't think blocking because of future ranking stuff makes sense, the current system is so simple and we don't even display rank XP anwhere, plus we're probably going to work on ranking very soon anyway, so if we completely break the current ranking stuff when doing this I don't think it really matters.

Assigning myself since I can only imagine myself or Gordi doing this, and he's busy for a while.

Lowering priority, not essential for map submission being "completed" and ready for people to start submitting stuff to, but we should definitely try to get this in 0.10.0
