Pushkar Umaranikar 9e54b29c4f Add service_token for nova-cinder interaction
Service token will be passed along with user token to communicate with
services when dealing with long running tasks like live migration.

This change addresses adding service_token to the request when nova
requests cinder session to interact with cinder.
