It is required for an external application to obtain the upstream service names of a target service in APM's Service Map.
For example(using the demo gallery), a query with productCatalogService to return checkoutService, frontend-node and recommendationService.

Please provide a query DSL or an API that would return all of the upstream service names for a target service.
Thank you!
