Enable/disable cluster Autoscaler for GKE clusters
When you create a cluster on GKE, it doesn't have cluster autoscaler enabled. We can provide the ability to turn it on/off, along with documentation about what this implies.
See https://cloud.google.com/kubernetes-engine/docs/concepts/cluster-autoscaler for more details.
In the cluster configuration panel, use a switch to enable/disable autoscaler.
