Taskmgr & guestagent use inconsistent topics
During a create instance call, the Task Manager needs to pre-create the
guestagent message queue so that it can send a "prepare" RPC before the
guest is running. It creates a topic queue called "guestagent.<UUID>".
When the guest starts up, it will attempt to create a topic queue
called "guestagent".
The overall result is that if the guest creates the queue it has a
different name than the task manager expects. This could happen if the
guestagent restarts after prepare. Both cases result in a queue being
created called "guestagent.<instance uuid>" because oslo.messaging
causes 3 queues per topic to be created (topic, direct and fanout) and
it so happens that the topic queue from task mgr matches the direct
queue from the guestagent, however, this doesn't appear to be
intentional behaviour.
This changes the guestagent topic name to match the taskmgr name.
