Public bug reported:

I am trying to run nova trunk with the oslo.messaging 1.7.0 in my lab.
Apparently, the notifications no long are sent.

After some investigation, here are the issues:

This line is trying to load the notifier driver:
https://github.com/openstack/nova/blob/master/nova/rpc.py#L65

Then this line here tries to load the drivers:
https://github.com/openstack/oslo.messaging/blob/1.7.0/oslo_messaging/notify/notifier.py#L132

And self._driver_names is a list containing
'nova.openstack.common.notifier.rpc_notifier'.

My understanding then is stevedore will enumerate through a list of
endpoints within "oslo.messaging.notify.drivers", one of them being
"nova.openstack.common.notifier.rpc_notifier -
oslo.messaging.notify._impl_messaging:MessagingDriver". Then stevedore
will attempt to load the latter class.  Unfortunately, only
oslo_messaging.notify._impl_messaging exists, and therefore driving
loading for notifier would fail.
