Support zonal not just regional GKE clusters

[jasonumiker]

It appears today (unless I've missed something) that it isn't possible to spin up zonal GKE clusters - just regional.

Since GCP allows one free zonal GKE cluster this is an important cost-savings measure ($0.10/hr or $876/year) for those of us doing testing/learning. https://cloud.google.com/kubernetes-engine/pricing#cluster_management_fee_and_free_tier

Hi @jasonumiker, you can opt for explicitly configuring the region and failureDomain so that only one zone during provisioning which effectively means that the cluster becomes a zonal cluster. You can take a look at the Machine Locations section in the CAPG book. Could you confirm is this is the functionality you are referring to?

I was revisiting this and found out that you specifically referred to GKE clusters. I'll try to take a look at how we can add support for this for managed clusters.
