examples: add the GlanceListImages example

simon3z · simon3z · commit a13e850d1d27 · 2013-03-27T15:22:45.000+01:00
This patch introduces a new example for the glance module. The example
authenticates to a known keystone instance to query the catalog and
retrieve the "image" (glance) services list.
Then it connects to the first glance instance and retrieves the list of
the available images.
