I don't think I'm alone within the cinder team in seeing significant
benefit to keeping plugins within the cinder code base - they benefit
not just from the eyes of reviewers, but also from the mindshare of
developers. Since we know (or can go and look) at how various plugins
are using (or abusing) the interfaces we provide, we can keep that in
mind when making changes, and fix up obvious cases. Once things are in
a separate repo, you get all sorts of painful version skew type
problems, and everybody has less insight into how the code behaves as
a whole.

The nature of some of the cinder drivers is that they require some
other services - e.g. some drivers snapshot to glace, all drivers
(should be able to) backup to glance, some drivers are tenant aware,
etc. Devstack is as good a 'standard platform' as we've got at the
moment... You could allow the validation suite to be run against any
openstack install, but then automated collection of the cinder.conf
and similar niceties becomes much harder.

+1 for John's approach
