[HELM] Fix Kubernetes Routing Issue

[piby180]

This PR aims to partially solve the issue mentioned here

With publishNotReadyAddresses set to true in service resource, kubernetes will publish the DNS address irrespective of whether the pod is in Ready state or not. Then the sole responsibility of when to start making requests to the newly restarted server/broker lies on Pinot.

The following error will be fixed with this PR

Unable to resolve host pinot-server-2.pinot-server-headless.pinot-dev.svc.cluster.local
or 
Unable to resolve host pinot-broker-2.pinot-server-headless.pinot-dev.svc.cluster.local
