title: Enable SNS Delivery Status Logging configuration in cloudformation
body: <p>I'm trying to set up an SNS topic with AWS CloudFormation.
  I'm able to get the topics and its SQS subscriptions up and running, but I couldn't find a way to specify the delivery status logging options (the ones that tell the topic to write its logs to cloudwatch).</p>
  
  <p>The <a href="https://docs.aws.amazon.com/es_es/AWSCloudFormation/latest/UserGuide/AWS_SNS.html" rel="noreferrer">official SNS/Cloudformation docs</a> say nothing about this capability.</p>
  
  <p><a href="https://www.reddit.com/r/aws/comments/b68pob/enabling_sns_delivery_status_logging_with/" rel="noreferrer">I found here</a> that apparently it's not implemented yet. Does anyone have up-to-date status about this?</p>
  
  <p>Below is the template (fragment) I have:</p>
  
  <pre><code>SNSBouncesTopic:
    Type: AWS::SNS::Topic
    Properties: 
      DisplayName: SNS-Bounces
      Subscription: 
       - Endpoint: !GetAtt
          - SQSBouncesQueue
          - Arn
         Protocol: sqs
      TopicName: SNS-Bounces
  </code></pre>
  
  <p>The SQSBouncesQueue is another resource of the stack that handles the SNS messages.</p>
