The offboarding steps are somewhat complicated. It'd be better if we could do something like select a user in the user manager and execute some kind of "offboard" action which:

1. expires all unexpired tokens
2. deletes all active django sessions
3. removes staff and superuser access
4. removes the user from hacker and hacker plus groups
5. leaves a big old item in the audit log

That'd be a lot faster and less error-prone than what we have now.
