Support 3GPP 28.532 APIs for slicing use case

Our aim is to build an O-RAN specific Macro flow-based NSSMF which can integrate with an external NSMF.  Current ONAP slicing use case is using 3GPP 28.531 APIs (Slice-Specific APIs). In addition we would like to provide support for 3GPP 28.532 APIs (as per Generic Provisioning APIs based on Managed Object Instances (MOI))

To achieve this goal: we have made changes in SO , OOF component and have pushed additional policy using Policy Component.

There is no change in SDC NSST design , also no change in the AAI slicing model
