docs: // IsRetriableError returns a boolean indicating whether the call that
  // generated the error can be retried.
  // When stopping a container, most errors that we can get should be
  // considered retriable. However, in the case where the container is
  // already stopped or doesn't exist at all, there's no sense in
  // retrying.
