Special notes for your reviewer:
for projects with no clusters we get following output for cluster list with a cluster name filter:

cluster list output: WARNING: The following filter keys were not present in any resource : name

deletion of non-existent cluster results in 404:

ERROR: (gcloud.container.clusters.delete) Some requests did not succeed:
 - args: ["ResponseError: code=404, message=Not found: projects/<project-name>/zones/us-central1-c/clusters/gcp-pd-csi-cluster.\nNo cluster named 'gcp-pd-csi-cluster' in mattcary-saikatroyc-test."]
   exit_code: 1

This is a temporary quick fix. we should use API client to create/list/delete GKE clusters.
