Enable cumulus with non-rackspace openstack (but using pyrax).

Tests look so much better that it would be crazy holding this back. Thanks!
Update pyrax, and make it stop reverting if the version is too new

Conflicts:
	setup.py
Add authors

Brandon Konkle and Thomas Schreiber to authors
use same pyrax version in tox as in setup.py
bump pyrax to 1.6.x and handle point releases better
New version

Released as 1.0.12
Merge branch 'master' into update-pyrax
