can not send notifier and RPC message in different rabbitMQ cluster

[wangjun]

I think notifier's and rpc's transports should be separated,just like this:

def init(conf):
    global TRANSPORT, NOTIFICATION_TRANSPORT
    global SENSORS_NOTIFIER, VERSIONED_NOTIFIER
    exmods = get_allowed_exmods()
    TRANSPORT = messaging.get_rpc_transport(conf,
                                            allowed_remote_exmods=exmods)
    NOTIFICATION_TRANSPORT = messaging.get_notification_transport(
        conf,
        allowed_remote_exmods=exmods)

    serializer = RequestContextSerializer(messaging.JsonPayloadSerializer())
    SENSORS_NOTIFIER = messaging.Notifier(NOTIFICATION_TRANSPORT,
                                          serializer=serializer)
    if conf.notification_level is None:
        VERSIONED_NOTIFIER = messaging.Notifier(NOTIFICATION_TRANSPORT,
                                                serializer=serializer,
                                                driver='noop')
    else:
        VERSIONED_NOTIFIER = messaging.Notifier(NOTIFICATION_TRANSPORT,
                                                serializer=serializer,
                                                topics=['ironic_versioned_'
                                                        'notifications'])

As I said in the patch's comment, what you were trying to do is that separating the destination of RPC calls and notifications. Now this title make me think that you are trying to send them into different rabbitmq clusters, which is little bit confusing.
