Ban and unban user via API
What does this MR do?
Epic: &5741
Issue: https://gitlab.com/gitlab-org/gitlab/-/issues/327354
Malicious actors create many issues in public projects/groups for spam. We need a way to be able to hide their issues until they can be reviewed and deemed safe. So we've introduced the ability for admins to ban users, which blocks the user and hides their contributions. Hidden issues cannot be accessed by non-admins. Admin users can still see the hidden issues so they can review the issues' contents.
For integrations, we need a way to set a user to this state via the API. This MR introduces the ability for instance administrators to ban and unban a user via the API.
A user cannot be banned via the API if the user is LDAP blocked, deactivated, or already banned or blocked. A user cannot be unbanned via the API if they are LDAP blocked, deactivated, or not already banned.
To ban a user:
curl --request POST --header "PRIVATE-TOKEN: $TOKEN" "http://127.0.0.1:3000/api/v4/users/<user id>/ban"
Unban a user:
curl --request POST --header "PRIVATE-TOKEN: $TOKEN" "http://127.0.0.1:3000/api/v4/users/<user id>/unban"
