ManagedClusterInfo uses deprecated region/zone labels[2.2]

Description of problem:

ManagedClusterInfo provides node labels for the UI via status.nodeList[].labels.

These include region/zone labels that have been deprecated since Kubernetes 1.17:
failure-domain.beta.kubernetes.io/region
failure-domain.beta.kubernetes.io/zone

https://kubernetes.io/docs/reference/labels-annotations-taints/#failure-domainbetakubernetesioregion

The preferred labels to use are. These are not currently captured in the ManagedClusterInfo instances.
topology.kubernetes.io/region
topology.kubernetes.io/zone

Version-Release number of selected component (if applicable):

All

How reproducible:

Most clusters still have the deprecated labels, but some platforms may have switched to using the newer labels exclusively (for example, a Bare Metal cluster installed with Assisted Installer might omit the deprecated labels).

Steps to Reproduce:

1. View the YAML for the ManagedClusterInfo for the cluster.

Actual results:

The old labels are included, but not the new preferred ones.

Expected results:

We should include the new labels. It may be safe to remove the old deprecated labels - need to determine if all supported Kubernetes versions will be using the newer form.
