    Add a retry_on_deadlock to reservations_expire

    Now that we have an index for the reservations_expire query, we
    have uncovered a race with quota usage updates due to the foreign
    key on the table, so just retry if there is a deadlock. This is
    a fix to unblock the gate while we try to remove the deadlocks
    completely.
