ecs-service: circuit breaker params are ignored

[johncblandii]

Describe the Bug

https://github.com/cloudposse/terraform-aws-components/blob/main/modules/ecs-service/main.tf#L259

deployment_controller_type = lookup(local.task, "deployment_controller_type", null) ends up passing in null which does not default to ECS for this conditional https://github.com/cloudposse/terraform-aws-ecs-alb-service-task/blob/main/main.tf#L642 so circuit_breaker_deployment_enabled and circuit_breaker_rollback_enabled never get enabled.

Expected Behavior

...
        task:
          circuit_breaker_deployment_enabled: true
          circuit_breaker_rollback_enabled: true

...should trigger...

      ~ deployment_circuit_breaker {
          ~ enable   = false -> true
          ~ rollback = false -> true
        }

Changing the values should trigger an update, but it requires manually setting deployment_controller_type: ECS.

Steps to Reproduce

Enable the circuit breaker for a task without explicitly setting the deployment controller.
