Generic cds payload for vnf/vf-module/service.

Things done-
-Fixed review comments.
-Added logic to create payload using scope and action.
-Populate instance parameters from SO-request to CDS payload for VNF.
-Implementation of setting orchestration status after CDS completes its operation based on SO scope.
-Make use of ControllerRunnable interface.
-Changed actionname to actionName to action.value as per Oscar's suggestion.
-Setting orchestration status after CDS completes its operation for VF-Module.
-Populate instance paraneters from SO to CDS for VF-Module.
