Put users into a pending state once `User Cap` limit is reached

Summary

When a SM instance reaches the Max Users limit created by the admin, users who are subsequently added or request access will go into a blocked_pending_approval state.

  • The admin should be able to approve individual user requests while the max value has been reached.
  • When the max is reached, users who are subsequently added or request access will go into a blocked_pending_approval state. reference
  • The admin will need to increase the max value if they would like open registration to continue.

Design

For the pending members feature, we're going to utilize this design: https://gitlab.com/groups/gitlab-org/-/uploads/52b8cb4df563dc7175b838ac705ffd16/Group_52.png, borrowed from https://gitlab.com/gitlab-org/gitlab/-/issues/21648

Testing & Availability

  1. blocked_pending_approval set to false for new user creation if user cap field is not set
  2. blocked_pending_approval for all new sign-ups is Require admin approval for new sign-ups is true
  3. blocked_pending_approval set to true for all new sign-ups once instance user cap is met

Update: per this comment we are using User Cap for this feature.
