horizontal_pod_autoscaling should be enabled by default

[czka]

You have horizontal_pod_autoscaling disabled by default. In Terraform (https://www.terraform.io/docs/providers/google/r/container_cluster.html) it's enabled by default though. Why have the opposite? It seems to me that generic Terraform modules should not change the default behavior of the original resources they are wrappers for, unless there's a good reason.
