title: What does @enablesns @enablesqs annotations do (spring cloud aws)?
body: <p>I have been trying to find documentation of @enablesns @enablesqs annotations but can't find them.</p>
  
  <p>They seem to be required for the sqs and sns integration to work.
  But I'd just like to have a better understanding, and be sure I'm not using them wrong.</p>
  
  <p>Any description would be of great help.</p>
