NcmpEvent creation and Mapping
- Mapping class to create header and event payload based on type of operation i.e CREATE, UPDATE and DELETE. - Service class to get CmHandle public properties, create event and delegate request to event publisher. - Modification in NcmpEvent schema json to mark field as String instead of URI - Test scenarios - UPCOMING: Call the service method from relevant code to actually publish the event. Issue-ID: CPS-1037 Change-Id: I6bb7de4b27e602c4d8ee6a5528a866e5f7e8799a Signed-off-by: mpriyank <priyank.maheshwari@est.tech>
