As a user of ONAP, I want SO to send an end of orchestration event when a given transaction is completed. This allows for other parts of ONAP, such as POMBA, to trigger activity knowing the orchestration flow is complete.  This event should contain the following information

• Mandatory
  • Resource identifier
    • Resource of top level flow, such as service instance id
  • Resource Type
    • Resource type of resource identifier, such as service
• Optional
  • Status of orchestration - success, partial success, error
  • State post orchestration - created, deleted, etc.
  • model instance id, model invariant id - references to object in SDC.

This event should be sent via DMaaP.   As this notification is going to be consumed as a means of triggering audits and other activity that assumes whatever piece of orchestration has reached a meaningful state, then this notification should either

• Only be sent when the orchestration is truly done from a macro perspective. For example, the service is successfully created and is functional
• The orchestration event is sent more frequently for finer grain orchestration but there is enough information in the notification so the consumer can react accordingly - ie tell when we are truly done or at a point that the consumer knows how to act upon.
