Run functional tests using keystone auth options

Makes the existing functional tests run using three
auth modes: tempauth (v1), keystone v2 and keystone v3.
The latter uses an account in a non-default domain
(which exists in devstack setup).

This should help avoid regressions in handling different
auth options.
