Goal

As a cluster admin, I want to manage the MachineSets on OpenShift using GitOps workflows so that I can recreate clusters or create multiple clusters with identical node setup.

More details on adding MachineSets:
https://docs.openshift.com/container-platform/4.9/machine_management/creating-infrastructure-machinesets.html#machineset-yaml-aws_creating-infrastructure-machinesets

The challenge with MachineSets i that it's an object owned by the cluster and contains attributes that are cluster-specific. Since the name of the MachineSet is specific to one cluster, applying MachineSets from a Git repo to multiple clusters does not work out of the box:

apiVersion: machine.openshift.io/v1beta1
kind: MachineSet
metadata:
  labels:
    machine.openshift.io/cluster-api-cluster: <infrastructure_id> 
  name: <infrastructure_id>-infra-<zone> 
  namespace: openshift-machine-api
spec:
 ...
