Audit additional details when blocking / unblocking users in GitLab

Description

Currently, when we block/unblock a user, the only details logged are the user id / username. This doesn't help tell us why a user was blocked / unblocked. We'd need to then manually look up these details should any issues occur.

Before blocking/unblocking, we need to log all GitLabUser attributes used in the decision:

• event description
• user_id
• username
• is_blocked_by_script
• is_external_user
• is_inactive
• current_sign_in_at
• created_at
• email

Also, after the block/unblock occurs, we just need to log the following:

• event description
• user_id
• username
