NATS server v2.2 introduced headers that can be used to post meta-data. More specifically, when a request is sent to NATS on a subject which no service is listening on, it can instantly send back a response with the Status header set to 503, indicating that the request has no responders.
Resgate should support dealing with Status 503 headers, turning them into system.notFound error responses.
Note
system.timeout would only be sent by Resgate if a service actually receives the request without responding in time.
system.notFound will be sent directly instead of the current 3 second delay waiting for the timeout.
