Fix ADC service discovery configuration syntax

Fixed service discovery configuration to use correct ADC syntax.
The namespace should be included in the service_name, not as a
separate namespace_id field.

Error:
✖ Unrecognized key: "namespace_id"
  → at services[0].upstream

Fix:
- Changed from: service_name: my-service + namespace_id: namespace
- Changed to: service_name: namespace/my-service

This matches the ADC/API7 expected format for Kubernetes service
discovery: "namespace/service-name"
