vm_vdi_cleaner.py fails to launch with NOTIFIER is not None AssertionError

[Jesse Keating]

I believe this has something to do with oslo messaging, in that it's attempting to set up a NOTIFIER and TRANSPORT for nova messaging, and failing.

vm_vdi_cleaner.py -v --command=list-vdis --config-file /etc/nova/nova.conf
