trove taskmanager_queue can not be changed

[jazeltq]

In the trove.taskmanager.api:API
we defined the target like this
        target = messaging.Target(topic=CONF.taskmanager_queue,
                                  version=rpc_version.RPC_API_VERSION)
But in the setupt of taskmanager, we defined like this:

 @with_initialize(extra_opts=extra_opts)
 def main(conf):
     startup(conf, None)

Then the topic can not be sent in. So we can not change the option CONF.taskmanager_queue.
If we change it in configuration file, the taskmanager can not get any message because it still declare on the default consumer queue.

    Sent in the topic when taskmanager setup

    The old setup won't sent the topic in, then we can not
    change the taskmanager_queue as we want. So add it.
