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

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  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.
