Description of problem: A warning needs to be placed wherever the Image Service (glance) multi-location function is described and configured: If configured without the proper policy settings, a non-admin user of the Image Service can replace active image data (that is, switch out a current image without other users knowing). See the OSSN announcement (recommended actions) for configuration information. Version-Release number of selected component (if applicable): All versions.

Tested builds successfully. Looks good to me. Merging request.
