[ECS [ALB Slow-Start]: Managed Load Balancer Slow Start Support for ECS Targets

Request for comment: please share your thoughts on this potential improvement to ECS:

Introduce a one click/command easier way to enable ALB slow start mode for ECS Service which allows the load balancer to linearly ramp-up the traffic to newly started ECS tasks. Users will be able to define a parameter ECS-Traffic-Slow-Start = “Enable” through the ECS/AWS-CLI or check a box in the console while setting up task definition to enable this feature.
Currently you can set-up your ECS tasks in such a way that allows you to warm-up traffic to your ECS tasks, but this workaround is complicated and does not solve for all use cases.

Review the ECS service and task-definition setup, along with the AWS CLI and console entry points mentioned in the request. Compare them with the existing workaround for warming traffic to newly started tasks. Done means the issue’s proposed ECS-Traffic-Slow-Start setting can be evaluated for both command-line and console use cases.
