Integration with the Cluster Autoscaler

Today KEDA can indirectly influence cluster autoscaling by causing the HPA to schedule too many pods so the cluster autoscaler kicks in and adds nodes. A common ask is to have KEDA potentially poke the cluster autoscaler even earlier the same way it pokes HPA before CPU + Memory hit. Not sure what integrations make this possible today, but would be a nice feature to be able to set some cluster threshold or something, or some way to describe driving cluster scale in addition to HPA scale.
