Give access to CredClient in tests
There are a couple of tests that rely on creating a new project and/or
user within the test that rely on the identity_client. This doesn't work
when we want to test with api_v2=False.
As part of the isolated credentials we already have an abstraction layer
for these identity operations. Extract the abstraction class into its
own file and add it to the base test class as identity_utils
(because I'm not sure what better name to call it).
