[ENHANCEMENT] Force 2FA on players with certain permissions.

[UserSv4]

I want users with certain permission (like limboauth.topt.force) to be forced to use 2FA so that if they don't setup 2FA, they wouldn't be able to join the server.

2FA could be set up right after /login or /register but before user actually gets to the server.

If user with this permission doesn't setup 2FA for a certain time period after logging in or registering he could just be kicked.

Discord has a similar feature.

I think this would be very useful for protecting server from admins' bad passwords. For example one could type /lpv group admin permission set limboauth.topt.force to partially protect server from admins using same password in multiple servers or services or just using a weak password.
