    Add support for using service tokens

    This patch configures nova-cloud-controller to send a service token
    along with the received user token on requests sent to other services.
    This allows those other services to accept the request even if the user
    token has been invalidated since received by the nova services running
    in nova-cloud-controller units, the same applies for incoming requests
    from other services. Service tokens exist since Openstack Queens.
