For now, all sandbox controller methods are implemented to return unimplemented errors (errdefs.ErrNotImplemented). Add an integration test to verify that containerd correctly routes sandbox API calls to our shim when configured with "sandboxer = shim" (or "sandbox_mode = "shim" for containerd 1.7), and that the shim returns the expected unimplemented error.
