This commit adds the ability to deploy the k8s cluster autoscaler using
local-exec rather than remote-exec.  Using local-exec is helpful when
you don't use the operator/bastion features of this module.  Now if you
set cluster_autoscaler_remote_exec variable to false terraform will run
a `kubectl apply` command on the same machine where you are running
Terraform.

This commit updates the autoscaler so when you want it to run locally it
will use the helm_release resource instead of a null_resource with a
local command provisioner.
