Remove Rackspace Auth Junk

https://repose.atlassian.net/browse/REP-17

Making a pull request to trigger the jenkins build. It's going to fail some integration tests, and I know this, I want it to fail so I can remove the ones that fail, or fix the ones that aren't supposed to be removed. I'm 80% sure I know which ones to remove already, but I don't have time to wait on the integration tests to run on my local box...

It passed! Good for review/pull now.
