Retry 3 times to log the action in the DB before bailing.
    
    This fixes an error that occurred recently on pagure over dist-git where
    suddenly we ran into a ``(TransactionRollbackError) deadlock detected``
    error.
    When this occurs, we will try to wait a little bit and come back to try
    logging the action, two times (meaning we tried three times to log the
    action).
    After this, we'll just bail and raise the error.
