[Fargate,ECS] [request]: Cluster deletion protection similar to ELB

**Tell us about your request**
It would be nice to have ELB-like deletion protection in ECS for clusters.

**Which service(s) is this request for?**
This could be Fargate, ECS.

**Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard?**
We share our account with several other teams, and from time to time it happens that a team member from other team deletes our cluster by mistake. All tasks/services running in that cluster wiped out. We can always recover using CI/CD but that sometimes takes time.

**Are you currently working around this issue?**
If the cluster gets deleted we can always reproduce it using CI/CD pipelines in place.

ELB deletion protection flag example

No implementation files, tests, or entry points are identified in the issue. Start by reviewing the ECS cluster deletion flow and comparing the requested behavior with ELB deletion protection; done means an ECS cluster-level protection option prevents accidental deletion while allowing an intentional removal path.
