Code Issues Proposed changes

Fix storing binaries in Swift 

* Swift does not work with Keystone API v3, so we need to always provide
   auth_url for API v2 to Swift.
 * We incorrectly parsed swift URL, which resulted in Sahara trying
   to get binaries from containers with '.sahara' suffix, while the
   suffix should be stripped.
