Failed to delete the clusters which failed before calling cluster_driver.create_cluster

[okozachenko1203]

The cluster creation has been failed at cert_manager.generate_certificates_to_cluster(). i.e. cluster_driver.create_cluster was not called and it means cluster.stack_id is none. Cluster-autoscaler helmrelease deletion is failed because its name is None.
