Instances flexible querying endpoint

[martinothamar]

Description

Storage has an endpoint with flexibile searching/querying that we don't expose in the app. We should probably consider exposing that.

Just had a case where SBS/external developer wanted to find active instance based on logged in user. It would be convenient to use SSN/org nr for that but for now we adviced extracting party ID from token and using the "active instances" endpoint in the app.

Så vidt jeg kan forstå er det grunnleggende problemet (eg. at instanceOwnerPartyId er ukjent for den som skal gjøre oppslag), løst ved å sette headeren X-Ai-InstanceOwnerIdentifier til Organisation:313541479 og bruke vanlig endepunkt direkte mot storage.

Så det som gjenstår er eventuelt å lage et proxy endepunkt så man kan bruke appens url i stedet for å sette ?appId={org/app}, og eventuelle andre filter for aktive instanser.
