We need to change the controlePlaneEndpoint of the k8s HA cluster as the LB Machine need to be replaced.

We have setuped k8s HA cluster last year on prem with a load balancer machine in front of the cluster by using kubeadm with config file like described here https://kubernetes.io/docs/setup/independent/high-availability/#steps-for-the-first-control-plane-node

The cluster should use another load balancer as endpoint and not the former one.
