The current implementation of envoy ALS K8S analysis is based on the hierarchy, pod -> StatefulSet -> deployment, StatefulSet, or others. It's freaky and different from the Istio Kubernetes registry.
The new path is pod -> endpoint -> service, and we should leverage Informer API instead of raw Kubernetes API.
