fix issue with Nova passthrough deprecation

Nova Networking was deprecated in Newton and some of the API calls
that were part of NN were still in use by Trove. With the arrival of
python-novaclient 8.0.0, this caused a failure.

Nova also deprecated the image pass through capability. The management
API uses some of that to test whether an image id is valid or
not. This change fixes the management API, and the attendant scenario
tests.
