Summary
Adds chart interfaces for topology-aware Kubernetes Service controls:
trafficDistributionsupport.loadBalancerClass,externalTrafficPolicy, andtrafficDistribution.loadBalancerClass,externalTrafficPolicy, andtrafficDistribution.metricsServiceso metrics can stay on ClusterIP while public LoadBalancer Services expose only libp2p.This PR is the chart dependency for the app-of-apps rollout PR. Deployment rationale and operational baselines live in internal tracking.
