eliminate callbacks for EXTERNAL_NETWORK

[Kevin Benton]

EXTERNAL_NETWORK is not a real resource. It's just a network with a specific attribute so having an independent callback is not necessary, nor do the semantics make sense (e.g. a network changing from external to non-external is a DELETE or an UPDATE?).

We should be able to get by with just NETWORK events.

    and adjusts the precommit update callback to include
    the request.

    Use NETWORK callbacks in get-me-a-network code

    This adjusts the get-me-a-network code to just
    rely on the regular NETWORK precommit events rather
    than the EXTERNAL_NETWORK events that the following
    patch eliminates.

    Remove EXTERNAL_NETWORK callbacks

    external networks are not really independent resources that
    have their own lifecycles independent from networks. The only
    use cases for this callback can be achieved with just regular
    NETWORK callbacks.

    The only users of this event have been adjusted to use NETWORK
    callbacks (according to codesearch.openstack.org).
