Yup. Keystone was actually next on my list to port to testtools. :)

In porting nova, I made use of the testtools matchers functionality and
self.assertThat. testtools.matchers.MatchesDict is, I believe, equiv to
unittest2's assertDictEqual. Additionally, in nova we made a DictEqual
matcher (crappy name, sorry) which does a deep match. We should probably
port that up into testtools itself.
