Added support for Keystone middleware feature to pass service token along with
the user token for Cinder to Nova and Glance services. This will help get rid
of user token expiration issues during long running tasks e.g. creating volume
snapshot (Cinder->Nova) and creating volume from image (Cinder->Glance) etc.
To use this functionality a service user needs to be created first. Add the
service user configurations in ``cinder.conf`` under ``service_user`` group
and set ``send_service_user_token`` flag to ``True``.
