Feature Request: Add SQS Redrive option to SNS event about serverless-application-model

[ConnorRobertson]

Hello @conao3
If you need to have custom properties (i.e. RedrivePolicy, VisibilityTimeout, etc) set on the SNS->SQS->Lambda generated AWS::SQS::Queue please define a custom SQS Queue. Then in the 'SNS' Event on the AWS::Serverless::Function reference the AWS::SQS::Queue in the SqsSubscription: like below. Please respond if you have any questions, or if this does not work for what you are trying to do.

Resources:
  Topic:
    Type: AWS::SNS::Topic

  MyFunctionTopicEventQueue:
    Type: AWS::SQS::Queue
    Properties:
      RedrivePolicy: 
        deadLetterTargetArn: 
          Fn::GetAtt: 
            - "MyDeadLetterQueue"
            - "Arn"
        maxReceiveCount: 5

              QueueArn:
