Recurring SQS Redrive rule for Terraform

[nmoutschen]

Follow-up of #79 but for terraform

What were you trying to accomplish?

Expected Behavior

If an SQS queue is a DLQ for another queue, it should not require a redrive_policy.

Current Behavior

Right now, all SQS queues require a redrive_policy per the aws_sqs_queue_redrive_policy rule.

Possible Solution

Inspect the redrive_policy of all queues and infer is a queue is a DLQ or not, then ignore the rule for those queues.

Steps to Reproduce (for bugs)

Environment

• Infrastructure as code technology used: Terraform
• (for cfn-lint) Python, cfn-lint, and cfn-lint-serverless versions: N/A
• (for tflint) Go, tflint versions: Skipping this
• Debugging logs

N/A

[nmoutschen]

Won't fix for now as TFLint cannot cross-reference resources based on dynamic values. See #107
