keystoneauth was split out last cycle as a library specifically to deal
with doing auth functions so that people who do not need to do keystone
CRUD operations can just consume only the auth session parts. As part
of modernizing keystone interactions, use keystoneauth instead of
keystoneclient.
A change to tests was made to stop checking how often the keystone auth
session is called. This could be broken in the future depending on how
the keystoneauth1 loader works. It is incorrect to mock out and check
how often Session is called when nova has no direct control over this.
The number of times barbican client is called is correctly in the
control of Nova and will continue to be tested.
