Missing ability to specify manage_draining for external_ec2 capacity provider in ec2.tf

[riccardomassullo]

Describe the Feature

As specified here Terraform docs for aws_ecs_capacity_provider the managed_draining option is ENABLED by default.

Expected Behavior

We should have a way to specify AT LEAST if should be enabled or not (like with the current managed_termination_protection setting)

Use Case

Being able to disable managed_draining on external ec2 capacity providers

Describe Ideal Solution

It could be achieved by simply adding a field to external_ec2_capacity_providers object:

variable "external_ec2_capacity_providers" {
  description = "External EC2 autoscale groups capacity providers"
  type = map(object({
    autoscaling_group_arn          = string
    managed_termination_protection = bool
    managed_draining               = bool
    managed_scaling_status         = bool
    instance_warmup_period         = optional(number, 300)
    maximum_scaling_step_size      = optional(number, 1)
    minimum_scaling_step_size      = optional(number, 1)
    target_capacity_utilization    = optional(number, 100)
  }))
  default = {}
  validation {
    condition     = !contains(["FARGATE", "FARGATE_SPOT"], keys(var.external_ec2_capacity_providers))
    error_message = "'FARGATE' and 'FARGATE_SPOT' name is reserved"
  }
}

and modifying the external_ec2 resource like this:

resource "aws_ecs_capacity_provider" "external_ec2" {
  for_each = local.external_ec2_capacity_providers
  name     = each.key

  auto_scaling_group_provider {
    auto_scaling_group_arn         = each.value["autoscaling_group_arn"]
    managed_termination_protection = each.value["managed_termination_protection"] ? "ENABLED" : "DISABLED"
    managed_draining               = each.value["managed_draining"] ? "ENABLED" : "DISABLED"

    managed_scaling {
      instance_warmup_period    = each.value["instance_warmup_period"]
      maximum_scaling_step_size = each.value["maximum_scaling_step_size"]
      minimum_scaling_step_size = each.value["minimum_scaling_step_size"]
      status                    = each.value["managed_scaling_status"] ? "ENABLED" : "DISABLED"
      target_capacity           = each.value["target_capacity_utilization"]
    }
  }
}
