Open Stack

Sam-

	Under the current design, you can provide a specific endpoint
(singular) via the `endpoint_override` conf option.  Based on feedback
on this thread, we will also be keeping support for
`[glance]api_servers` for consumers who actually need to be able to
specify multiple endpoints.  See latest spec proposal[1] for details.
