Expose uniqueid of task_exec role

[missylbytes]

Describe the Feature

An output of the unique IDs for the two roles created for the service task:
task_exec_role_uniqueid

Expected Behavior

When using this module, I can access the uniqueid (https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/iam_role#unique_id) field on the task_exec role.

Use Case

We use the unique ids for permissions for secrets. Since I cannot access the uniqueid on the task_exec role, we have to do a chicken and an egg scenario of trying to access these fields through a data source:

# These are needed because the cloudposse module does not expose the roles unique ids
data "aws_iam_role" "task_exec_role" {
  name = module.ecs_alb_service_task.task_exec_role_name
}

Describe Ideal Solution

As stated above, just an output of the uniqueid for the task_exec role

EDIT: I do see that the task role is the unique ID. So really just need the task_exec role's uniqueid.
