Updated google_container_cluster

[night-gold]

Added precision on the valid subnet for 'master_ipv4_cidr_block' in 'private_cluster_config' block.

Sorry for the delay on our end @night-gold- do you have a source for that value needing to be /28? It doesn't look like that's reflected on the GKE docs.

[night-gold]

I tried it with terraform and it was in the error message.

In the deprecated way of doing it, that has been removed, it was already written that it should be a /28 CIDR for it to work.

I can also confirm the /28 limitation for masters in private clusters. Here are the supporting docs: https://cloud.google.com/kubernetes-engine/docs/how-to/private-clusters#limitations

Thanks @night-gold! I'm going to push a commit to clean up the wording slightly, and then this will be good to go 👍
