    Ensure fip ip rules deleted when fip removed

    The information needed to delete ip rules associated
    with fips is held in memory between add and remove so
    a restart of the l3-agent results in any fips that
    existed before the restart having their ip rules
    persist after the fips are removed. This patch
    enures that an agent restart reloads this information
    so that ip rules associated with a fip are correctly
    removed when the fip is removed.
