Public bug reported:

The recent change to oslo messaging seems to have removed the ability to
specify a list of topics for notifications.   This is a critical feature
for systems which provide multiple message streams for billing and
monitoring.


To reproduce:

1) Create a devstack system

2) Add the following lines to the [DEFAULT] section of nova.conf:
notification_driver = nova.openstack.common.notifier.rpc_notifier
notification_topics = notifications,monitor
notify_on_state_change = vm_and_task_state
notify_on_any_change = True
instance_usage_audit = True
instance_usage_audit_period = hour

3) Restart all the n-* services

4) Look at the info queues in rabbit
sudo rabbitmqctl list_queues | grep info
notifications.info      15

5) Create an instance
ubuntu@devstack-net-cache:/mnt/devstack$ nova boot --image cirros-0.3.1-x86_64-uec --flavor 1 phil2

6) Look at the info queues in rabbit
sudo rabbitmqctl list_queues | grep info
notifications.info      17


Messages are being added to the "notifications" queue, but not to the
monitor queue
