Allow conversion of user accounts to service accounts
With Service accounts seeing greater adoption, a user may want to convert previously creature human type user accounts into service accounts while keeping the same username/ID etc. Some of the considerations would be ensuring the limitations for service accounts are correctly applied when such an action is performed e.g Interactive logins are disabled, licence/tiering restrictions for service accounts are added, password expiration policy is matched. Only Instance admins or top level group owners will be able to perform such an action
A simple UI for this could be a button on the top level group to select an existing member and convert to service account
