/**
 * Convenient factory bean for creating a stateless retry interceptor for use in a
 * {@link StreamListenerContainer} when consuming native stream messages, giving you a
 * large amount of control over the behavior of a container when a listener fails. To
 * control the number of retry attempt or the backoff in between attempts, supply a
 * customized {@link RetryTemplate}. Stateless retry is appropriate if your listener can
 * be called repeatedly between failures with no side effects. The semantics of stateless
 * retry mean that a listener exception is not propagated to the container until the retry
 * attempts are exhausted. When the retry attempts are exhausted it can be processed using
 * a {@link StreamMessageRecoverer} if one is provided.
