AWS::SQS::Permission

## 1. Title

AWS::SQS::Permission

## 2. Scope of request

AWS::SNS::Permission - can add permission to a SQS queue via API but not via CloudFormation

## 3. Expected behavior

In Create, it should add a new permission to the SQS queue policy, the same as `aws sqs add-permission`
In Update, it should replace the existing permission, as if one performed `aws sqs remove-permission` and then `aws sqs add-permission` (since there's no `update-permission`)
In Delete, it should remove the existing permission, the same as `aws sqs remove-permission`
