Comment 7 for bug 1277204

Did some more debugging in Devstack after the two above were merged, but flumxed as to why notifications still don't work.

I can see the notification message reaching published_send() method in oslo/messaging/_drivers/_impl_rabbit.py with a topic of "notifications.info", and can see from the same set of tracing normal Nova messages being sent to a topic of "conductor"

But while the conductor messages clearly get there, the notification ones just never seem to make it to the queue, even though Neutron (which hasn't yet moved to oslo messaging) are going into the notification.info queue (so the queue itself exists)
