Jamie added some excellent "Using Sessions" docs to keystoneclient in I5e44c1029ce160cb2798cfb8a535aa9f3311799a. These will be published to http://docs.openstack.org/developer/python-keystoneclient/using-sessions.html once the version after 0.9.0 is released. Let's add a brief example on how to use this API and reference the keystoneclient docs. Change-Id: Icbcef45f13c1f962c90aa3db9dde4360520166ff
