Subject: Add tests for OSC usage

OSC uses os-client-config as an intermediate handler in the
argparse-to-final-options sequence.
* Validate the expected usage of the argparse arguement to get_one_cloud().

This turned out to be a problem with the way set_defaults() was implemented
and has been withdrawn until set_defaults is re-worked as a kwarg to
OpenStackCloud.__init__()
* Validate setting the default auth_type value
