Add server test for image and flavor lookups

Review Ia66e44e530799ce6531922dcf6a84e38528c8725 changes OSC's server
commands to use the image client rather than compute clirnt (yay!)
but we never really tested any of this in functional tests.  This review
adds a simple functional test (in the new style) to watch the client
change; it passes locally for me without the client change, due to timing
we went ahead and merged that first.
