unable to GKE update node version when there are multiple pools

[Stono]

Hi there,
We have quite a complex GKE setup which uses a google_container_cluster, and then 3x google_container_node_pool as well.

When we come to update the node_version today, we're getting this error:

* module.k8-elastic-cluster.google_container_cluster.cluster: 1 error(s) occurred:

* google_container_cluster.cluster: googleapi: Error 400: Node pool id must be specified if cluster has more than one node pool.., badRequest

So it looks like the google api is wanting you to specify which pool to upgrade so behind the scenes you'd need to iterate over each node_pool and one by one (as you can only do one at a time) upgrade them.

Future
I would suggest that the node_version should actually be an attribute on google_container_node_pool, as pools can be on different versions.

Closing this since it's a duplicate of #633 and is already fixed by #1266 (which will be in the next release, likely next week but no promises)
