thanks for opening the PR to enable autoscaling for AKS clusters @zmalik!

Going to retitle this issue to reduce scope to managed clusters (which is what the PR does already). For regular MachinePools, we still need kubernetes-sigs/cluster-api#4063 to be done in order to support cluster-autoscaler. @mboersma is already working on it.
