Enhancement Description

• One-line enhancement description (can be used as a release note):

The topology labels by cloud providers we apply on nodes have been in "beta" for a very long time. Given their usage across the project we should GA them.

The 3 labels are:
beta.kubernetes.io/instance-type
failure-domain.beta.kubernetes.io/zone
failure-domain.beta.kubernetes.io/region

They should be renamed to:
node.kubernetes.io/instance-type
topology.kubernetes.io/zone
topology.kubernetes.io/region

While keeping backwards compatibility in mind. Changing the label format may also be an option given we have to rename the label key anyways.
