This patch adds a small script that automates the process of accessing a
service provider (SP) cloud using credentials from a identity provider
cloud (IdP), where both clouds use Keystone based authentication. The
script performs the complete authentication flow and displays the token
and endpoints to use with the openstack command line client.
