Adding /quarantine and /unquarantine

[Zabuzard]

Overview

This adds the /quarantine and /unquarantine commands. They act mostly as preparation for #394 , but should also aid as help for mods and staff to manually resolve situations.

Quarantining is similar to muting, but will have subtle differences in how it is handled in the server, permission-wise. For example, a quarantined user might only be given access to a special #quarantine_zone channel, where he can talk to the moderators. Also, they will have less permissions than muted users, for example not being able to view any other channel anymore.

Quarantines are permanent, but the code supports temporary quarantines as well (this will be interesting for the scam blocker).

Details

This is mostly a copy&paste&edit of mute. Touched stuff:

Commands:

• QuarantineCommand
• UnquarantineCommand
• added enum values in ModerationAction
• added role helpers in ModerationUtils

To auto-revoke temporary quarantines:

• TemporaryQuarantineAction
• edits in TemporaryModerationRoutine

To reapply the role after rejoin:

• merged existing RejoinMuteListener with quarantine into more general RejoinModerationRoleListener

Config

This changed the config. See the template:

"quarantinedRolePattern": "Quarantined"

Smells are code duplication. The duplication is between mute and quarantine. While it is correct, I think it might be better to have the duplication. Overly coupling both actions would result in a pretty messy code that is hard to view isolated.

After all, the two commands serve different purposes.

An argument could be made to abstract both to some sort of "apply role" commands. Maybe it is worth pursuing this direction, but the claimed duplication is actually mostly on the user-responses and command layout, which wouldnt be covered by such a merge anyways...

So for the same reason we accepted the duplication between ban, warn and mute, I am voting to accept it here as well.

Mr Styling has returned, besides that;

I'm fine with ignoring the code duplication, so 👍 from me
