### SIG Autoscaling

* A cluster-autoscaler ClusterRole is added to cover only the functionality required by Cluster Autoscaler and avoid abusing system:cluster-admin role. Cloud providers other than GCE might want to update their deployments or sample yaml files to reuse the role created via add-on. ([#64503](https://github.com/kubernetes/kubernetes/pull/64503), [@kgolab](https://github.com/kgolab))
