    Fix way of calculate LB status after HM event

    Function _get_new_operating_statuses was calculating the
    LB status based on the received event together with
    current operating_status of the members, those values
    were not being stored and therefore were not available
    for the calculation.

    Now those member status are stored in the external_ids
    field related to the LB under the neutron:member_status tag,
    where the uuid of the member and its current status are
    stored.

    This way we can calculate the real-time status of the whole
    LB hierarchy by looking at the values stored there, which
    are updated when HM events are received.
