Update A&AI schema with Network Slicing model

Need to check whether this is needed.

Enhance ONAP model with Network Slicing related constructs

Provide a demo Network Slicing SDC model

• Config policy for slice allocation, slice sharing, slice sub-net allocation and slice sub-net sharing
• Config policy for resource allocation for a slice sub-net
• Config policy for optimization constraints – e.g., network resource optimization, resiliency, etc.

• DGs for receiving DMaaP message from SO with RAN NSSI details, map them to netconf messages and send to RAN.
• Interaction with PNF PnP to be discussed
• Config DB – could leverage existing Config DB and extend it.Runtime DB interaction

• CSMF impacts, workflows for service instantiation, involving service decomposition, NST selection, NSI allocation trigger, service instantiation
• NSMF impacts, workflows for NSI selection, NSI instantiation, NSSI selection, trigger for NSSI instantiation, NSI activation
• NSSMF impacts under discussion with ArchCom
• Interface to external NSSMF
• Store slice catalog items, update active slice inventory
