  [SRU] Juno nova-* ImportError: No module named rootwrap.cmd (when used
  without neutron)

Bug description:
  Following Juno 2014.2.4 and related SRUs:
  https://bugs.launchpad.net/cloud-archive/+bug/1518323
  https://bugs.launchpad.net/nova/+bug/1353939

  When neutron is not related, nova-* services fail on nova-compute
  units with ImportError: No module named rootwrap.cmd

  juno nova-*, from the perspective of our existing amulet tests, is
  definitely broken following recent Juno SRUs in the cloud archive.
  I've re-confirmed that the amulet tests were passing for nova-
  compute/next prior to these updates.

  juno nova-*, from the perspective of our full deployments, seems to be
  fine following the same.  These full deploys are the tests, along with
  tempest, which are exercised during the staging and proposed period.

  To differentiate:  the amulet test has a minimal topology which
  doesn't include the neutron-*, whereas the full deploy does.

  Granted, nova-network was to-be, then not-to-be deprecated in Juno.
  Ultimately, as I understand it, upstream decided to hold that
  deprecation until certain feature parity was met in neutron.  It may
  exist, but I've not located an indicator of anyone actually pulling
  the nova-network deprecation trigger on Juno.

  This issue causes amulet tests to fail for the following openstack-charms, where those tests include nova without neutron:
   - ceilometer
   - heat
   - nova-cloud-controller
   - nova-compute
   - (This list may not be complete, still reviewing.)
