Ban System

[TroyKomodo]

Adding the ability to ban and unban people

[intro23]

For this feature to be complete it implies there are users with ManageUsers global role. Should a query to show a users global roles show be included with this?

When banning should we allow for banning multiple users in one request or just one user?
When banning someone who is already banned what is expected behaviour for each of the cases (banned with expires_at set and expires_at unset)?

When unbanning should the entry be removed from the table or set the expiration to now?

i think the ban system is a bit far without the role system first.
allowing multiple bans vs 1 is an easy change but we need a proper permission system
