This ensures that the files are in sync with: hostpath: v1.2.0-rc3 external-attacher: v2.0.1 external-provisioner: v1.3.0 external-resizer: v0.2.0 external-snapshotter: v1.2.0 driver-registrar/rbac.yaml is obsolete because only node-driver-registrar is in use now and does not need RBAC rules. mock/e2e-test-rbac.yaml was not used anywhere. The README.md files were updated to indicate that these really are files copied from elsewhere. To avoid the need to constantly edit these files on each update, <version> is used as placeholder in the URL.
The original file is https://github.com/kubernetes-csi/external-resizer/blob//deploy/kubernetes/rbac.yaml
