A&AI allows the nodes query to access service instances without having to specify the hierarchy of customer and service-subscription.

https://docs.onap.org/en/latest/submodules/aai/aai-common.git/docs/AAI%20REST%20API%20Documentation/nodesQuery.html

This task will update the Service Inventory API

GET https://{extapi_url}/nbi/api/v4/service/{serviceinstanceid}   without having to pass either the serviceSpecification.name or serviceSpecification.id ( which is what they were trying to find by querying the inventory ), and also the relatedParty.id ( customer ) as in RequestParams.

From A&AI we can use

aai/v14/nodes/service-instances/service-instance/{id}

For GET

https://{extapi_url}/nbi/api/v4/service/ 

for list of services we can support get all services using

e.g. aai/v14/nodes/service-instances/

or also get a filtered list of all services for a specific customer

https://{extapi_url}/nbi/api/v4/service/?relatedParty.id=Demo

using the existing queries from Casablanca

i.e. the filter is optional
