After migrating a cluster's worker node instances with larger instance types, multiple cluster operators are degraded and authentication and console cluster operators are not available.

Replace loaded worker nodes with larger instance types and perform cluster health check.

1. Create a cluster with 3 master nodes ('m5.xlarge') and 30 worker nodes ('m5.xlarge') with OVN.
2. Run kube-burner cluster-density workload (https://github.com/cloud-bulldozer/e2e-benchmarking)
3. Note CPU and Memory resource usage of Master nodes
4. Create a new machineset of 15 worker nodes with ('m5.2xlarge') instance type.
5. Scale down existing machineset (using 'm5.xlarge') one at a time to 0.
6. All cluster-density pods should be successfully migrated to new machineset.
7. Delete all cluster-density namespaces
8. Rerun kube burner cluster-density test on the cluster with only new machineset.
9. Notice that the test fails trying to get Route for prometheus and when you check cluster health: authentication, console and ingress cluster operators are reported as degraded.

No cluster operators should be degraded.
Should be able to run kube burner cluster-density workload successfully on new machineset.
