My two cents: all python bindings should rely on python-keystoneclient
for obtaining token and url from catalogue, rather than duplicating the
logic to get a token and parse the catalogue, like cinder and nova
client do. This will make it easier in future to support new version of
the identity API.

** Also affects: python-novaclient
