python-novaclient's functional tests don't run with python-keystoneclient 3.0.0

[Tony Breeds]

python-keystoneclient 3.0.0 removed the 'keystone' command. tempest-lib depends on that tool existing[1]. This causes an issue for any tests that call out to keystone via tempest-lib

ie: http://git.openstack.org/cgit/openstack/python-novaclient/tree/novaclient/tests/functional/test_quotas.py?h=stable/liberty#n27

results in:

novaclient made their functional tests pass by using the keystone API python bindings, basically just making a client and calling what they needed, the exact commit is here: https://github.com/openstack/python-novaclient/commit/d133a664ae19385ded69ee416f04f6243c26285e

can we just backport this to stable/* ?

are there other jobs that are failing?

[Tony Breeds (o-tony)]

That's an interesting idea. So far I've only seen failures in python-novaclient. I'll check to see if any other tempest-lib users use the cli_clients.keystone() method
