Automated User Management Functionality
Description
User management can be difficult and time consuming for Admins. GitLab should make user management easier via some automation.
Proposal
One nice feature would be the ability to automatically disable a user account (or delete if desired) if they haven't logged in after X number of days/months.
This would be an effective way of "freeing up" licenses after a quarterly true-up. Plus it would make cleaning up a server a lot easier for Admins.
