Is your request related to a problem? Please describe.

We want to enable AWS managed ECS draining for our ECS clusters. For new capacity providers, this is enabled by default but for existing it needs to be explicitely enabled.

Add managed_draining property into aws_ecs_capacity_provider resource.

So I had thought that someone had made an issue already and implemented this via #174 problem is I don't know the process here and am wondering when this update is getting pushed out for this module. I've been waiting for this update as well.
