Resize google_container_cluster without destroying and re-creating

[hashibot]

This issue was originally opened by @devth as hashicorp/terraform#5622. It was migrated here as part of the provider split. The original body of the issue is below.

---

GKE supports resizing an underlying compute cluster on the fly:
https://cloud.google.com/container-engine/docs/resize-cluster

google_container_cluster's initial_node_count describes the initial count; if you change this the cluster is destroyed/re-created.

The docs describe getting at the underlying managed instance group gke-example-b937f2ba-node.

How can we do this in Terraform?
