1. Proposed title of this feature request

Support setting VM tags in Hive

2. What is the nature and description of the request?

Since OpenShift 4.16, it is possible to set tags on Machines using MachineSets as seen here: https://docs.redhat.com/en/documentation/openshift_container_platform/4.16/html/machine_management/managing-compute-machines-with-the-machine-api

However, this feature has not been propagated to Hive, even though it seems like a minor change. We have submitted a PR that we believe implements this feature in Hive: https://github.com/openshift/hive/pull/2737 

3. Why does the customer need this? (List the business requirements here)

This is very important for us because we need tags to exclude our worker VMs from backup-processes that snapshots our VMs and cause disks to get locked to the nodes. 

4. List any affected packages or components.
