    Bagpipe driver: use Neutron registry not an ML2 MD

    This change makes the bagpipe driver use the Neutron
    registry callbacks instead of a custom ML2 mech driver.

    The now obsolete bgpvpn_notify mech driver still exists
    to avoid breaking past configs, but it is empty and logs
    a warning on startup.

    With this change, the bagpipe driver also stops
    preventing network deletion, because without a mech driver
    we can't, which is good since it fixes bug 1489881.

    This change also changes the behavior to ignore DHCP ports.

I will close this bug, because DHCP is now covered and I think we shouldn't ignore Router Ports.

    bagpipe driver: missing return to ignore DHCP ports

    Really ignore DHCP ports (there were two missing returns).
    (+fixes in a few log messages).

    Also adds new test cases on to check the callbacks-to-RPC
    logic, including one to confirm that DHCP port are indeed
    ignored.
