USHIFT-6951: Add standalone cluster-monitoring-operator rebase script

Move kube-state-metrics rebase logic out of shared assets.yaml/rebase.sh into
rebase_cluster_monitoring_operator.sh with a matching assets recipe. The script
is identical across sibling PRs (openshift#6808, openshift#6809, openshift#6810) to simplify merging the
three optional monitoring components.
