Support Placement Constraints for Grant 

Grant for 3rd-party NFVO is improved. Process related to placement
constraints is supported. This enables interoperability with
3rd-party NFVO which enables them to deploy each VM in the VNF after
setting the zone information based on the grant response from NFVO.
