Make glanceclient accept a session object

To make this work we create a different HTTPClient that extends the
basic keystoneclient Adapter. The Adapter is a standard set of
parameters that all clients should know how to use like region_name and
user_agent. We extend this with the glance specific response
manipulation like loading and sending iterables.

Implements: bp session-objects
