Error provisioning cluster on gke

[markito]

After running the bootstrap scripts on Configuring GKE for Multi-Cluster Operation with Istio lab - the GKE cluster creation fails. The logs on the workDir reported the following:

###
### Begin Provision GKE
###
Creating cluster...
ERROR: (gcloud.beta.container.clusters.create) unrecognized arguments: --identity-namespace=qwiklabs-gcp-00-697400
0201df.svc.id.goog (did you mean '--identity-provider'?)
To search the help text of gcloud commands, run:
  gcloud help -- SEARCH_TERMS

Provisioning of the remote cluster also reported some weird errors:
