    Fix amphorav1 member deletion bug

    When the worker calculates the delta for plugging/unplugging subnets,
    it need to check the provisioning_status of the members. But in
    amphorav1, this status comes from the LB DB object that is passed to
    taskflow. If the provisioning_status is modified by another task
    (MarkMemberPendingDeleteInDb), the LB object is not updated.
    We need to reload it from the DB to get the current status of the
    members.

    Note: this patch is for stable branches only as the amphorav1 driver was
          removed during the Bobcat cycle
