SO NFVO needs to enhance NS LCM and Workflows management - validate if it works with 3.3.1

• The NS LCM Manager component in SO NFVO needs to enhance the following NS orchestration operations by leveraging NS workflows and business logic.
  • CreateNS
  • InstantiateNS
  • TerminateNS
  • DeleteNS 
• The default NS workflows and business logic need to enhance the following NS workflows:

• • CreateNS bpmn files with business logic
  • InstantiateNS bpmn files with business logic

• Note: when ONAP Dynamic BPMN is available, follow the "Package and deploy NS LCM Workflows with business logic" use case.
