    Notify nova when ports are ready

    The following patch adds a callback from neutron to nova that notifies nova
    when a port for an instance is *ready to be used*. After nova receives this
    event it will then start the instance in a hope that when it comes up
    its networking should be in working order.

    NOTE: *ready to be used* currently means that a plugin changes the status
    in the db associated with a port from:
    NO_VALUE/PORT_STATUS_DOWN/PORT_STATUS_ACTIVE to ACTIVE/ERROR.

    Neutron will then signal nova: network_vif_plugged:<status> where status
    will either be 'completed' or 'failed' given the neutron port status.

    Neutron also notifies nova when a port goes from status:
    PORT_STATUS_ACTIVE to PORT_STATUS_DOWN and sends nova a network_vif_unplugged
    event.

    Currently this patch breaks multiregion support (i.e previously you could
    back multiple nova regions by one neutron server) though now since neutron
    needs to notify nova we'll need to add a way to determine which region a
    given port is in.

    For now the work around for this would be to set: notify_nova_port_active=False
    in neutron to prevent neutron from sending the notification and setting:
    vif_plugging_is_fatal=False in nova.conf. Doing this will keep the current
    interaction where an instance will be booted without waiting for the network
    to be ready.

    Update flags and tables for neutron

    Remove unneeded xi:include (metadata agent is not a plug-in)

    Provide tables for new plugins and ML2 mechanisms

    To avoid breaking the large tables appearance by using xrefs, the
    bigswitch table is generated twice (one table for the ML2 mechanism, one
    table for the standalone plugin). This is a (hopefully) temporary
    change. Tables generations will probably be updated in Juno.
