Leverage ECS circuit breakers to fail ECS deployments

There is a new ECS feature called "deployment circuit breakers" -- https://aws.amazon.com/blogs/containers/announcing-amazon-ecs-deployment-circuit-breaker/ -- that should be used by the RFDK during its ECS-based deployments.

### Use Case

The current RFDK cannot fail a deployment of its ECS-based components (Deadline RenderQueue & UsageBasedLicensing); if there's a misconfiguration leading to a failed deployment, then the ECS task will just repeatedly fail and restart, but the CloudFormation deployment will succeed. It would be much better if the CloudFormation deployment also failed in this situation.
