Update Ranger logic to pass the X-Auth-Token in the headers when
creating or updating a ranger resource (flavors, customers,
images, and groups).
Update rds logic to generate a token before making the delete
region request.
These changes are necessary as user authentication logic has been
implemented for RMS region creation and updates.
