    Re-factor and improve update_networks_matching_iface_port

    * Implement _find_best_match() using subset intersection.
    * Reduce number of expensive external neutron calls to get net_id by
      moving this outside the inner loop.

    Unit test updated, we now do a better job at matching and populate more
    data when updating.
