Refactor k8s-integration to use GKE go client SDK

[verult]

Today gcloud doesn't allow disabling of addons on cluster creation, so in our tests, to avoid running a cluster update, ideally we use the GKE SDK and call the API directly.

I believe this is the client: https://pkg.go.dev/cloud.google.com/go/container/apiv1
