title: AWS ECS capacity provider using terraform
body: <p>I'm trying to add to my existing infrastructure managed by terraform a capacity provider for ECS cluster. Terraform apply returns with no errors, the new resource is added in the state file, but surprise surprise it doesn't appear in AWS GUI (ECS cluster->Capacity provider -> No results). 
  If I use aws cli to list this resource outputs fine, also rebuilding everything doesn't help.
  Has anyone succeeded in adding capacity provider for ECS using terraform?</p>
  
  <p>(I'm using provider version: “2.45.0”)
  Thank you!</p>
