As the GCP Filestore user I would like all the resources belonging to the cluster to be automatically deleted upon the cluster destruction. This is currently only working for GCP PD volumes but has to be done manually for GCP Filestore ones:

https://docs.openshift.com/container-platform/4.13/storage/container_storage_interface/persistent-storage-csi-google-cloud-file.html#persistent-storage-csi-gcp-cloud-file-delete-instances_persistent-storage-csi-google-cloud-file

Exit criteria:

• All the cluster provisioned GCP Filestore volumes are labelled as belonging to a cluster
• All the labelled GCP Filestore volumes are removed from the cloud when the cluster gets destroyed.
