Add vsg,vrouter relative code for short term

(1) once onos synchronizer does not depend on vsg and vrouter,
    we should remove vsg and vrouter from M-CORD
(2) changed the compute node name
(3) comment the CORDSubscriber and CORDUser relative code inside setup.yaml for now,
    because currently, this two objects are inside olt service.
