feat: temporary privilege escalation for staff

[Vuks69]

Idea

A time based temp admin feature.

This would allow normal accounts to have less perms in practice (think of it like you would not want to daily drive a machine as root).

Relevant module

Administration or Moderation

Flow

• [User] in a certain server staff group (like %wheel in NGL, the detail isn't hammered out) runs the command
  • Required "Reason" field
• Bot sends a request to a designated channel where only [Approved] (again another role) people can vote/accept that request
  • Requester can not approve their own request
  • Configurable # of approvals required, >=1
• User is given the privileged Discord role until one of the following happens:
  • A configurable amount of time passes
  • User runs a command to end their privilege escalation early
  • An Approved user runs a command to end the privilege escalation early
    • This could be extended to less-privileged roles, so that there are more hands able to stop a rogue user
• Bot removes the privileged role from the user

Security concerns

This should probably not be used for the Administrator permission, as it is extremely powerful - damage can be done even with Wick's antinuke.
