title: Manual ack with Spring Cloud Stream RabbitMQ
body: <p>I'm trying to setup a scenario where the listeners will manually send ACK to RabbitMQ. I have this in my application.properties</p>
  
  <pre><code>spring.cloud.stream.rabbit.bindings.input.consumer.acknowledge-mode=MANUAL
  </code></pre>
  
  <p>How do I send an ack from the listener?
  I see from <a href="https://stackoverflow.com/questions/37822252/manual-acknowledgement-of-messages-spring-cloud-stream-kafka">Manual Acknowledgement of Messages : Spring Cloud Stream Kafka</a> that for Kafka, we create an Acknowledgement object and call acknowledge() in it. Is there an example for RabbitMQ to do the same?</p>
