Follow-up to https://issues.redhat.com/browse/MCO-532 to be implemented in 4.15.

This can be done by creating dummy manifests for the two configmaps("machine-config" and "machine-config-controller") in question and setting an annotation like this: 

.metadata.annotations["release.openshift.io/delete"]="true"

This should delete the configmap when an upgrade to this version takes place. 

Done When

• Cleans up old ConfigMaps that were being used as leases
• No weird/unexplainable timings/errors are introduced
• Tests pass
