Use “format” query parameter on Node Query to find service instance hierarchy

There are a couple of useful values available for the “format” parameter for your case, in particular:

https://onap.readthedocs.io/en/casablanca/submodules/aai/aai-common.git/docs/AAI%20REST%20API%20Documentation/customQueries.html#simple

i.e.

?format=resource_and_url
?format=simple

The output format will include a URL parameter with the value being the full path to the object, e.g.

"url": "/aai/v11/cloud-infrastructure/complexes/complex/complextest1"

So in the case of the service-instance URL, it should give you the global-customer-id and service-type parameters in the path

We can use this in the get service/{id} API to retrieve relatedParty
