    List ports when attempt to delete network with ports

    When there is attempt to delete network with ports,
    a general error message is displayed that one or more
    ports are in use on the network. This patch proposes
    to also return the ports which are in use as part of
    the message.

    Also modify test_delete_network_if_port_exists unit
    test to check for port id and network id in Error
    message.

    Also bump required version of neutron-lib to 2.18.0
    as that's needed for custom message in NetworkInUse
    Exception.
