All Implemented Interfaces:

public class ControllerInstanceTagRefresher
extends Object
implements org.apache.helix.PreConnectCallback

If the instance is already a participant of the cluster, then we need this logic to update Instance tags in the case of K8S assigning this controller participant to another cluster
