[Enhancement]: Support tags attribute in aws_appautoscaling_policy

[RJKeane2000]

Description

The aws_appautoscaling_policy resource creates CloudWatch metric alarms on our behalf. We're able to retrieve the arns of these alarms through the alarm_arns output attribute. CloudWatch metric alarms support tagging.

Can you add the "tags" attribute to the aws_appautoscaling_policy resource so that it can pass the tags to the generated CloudWatch metric alarms? Currently I run script in our pipeline to retrieve the alarm arns and execute the AWS CLI to tag each alarm accordingly.

I've also tried setting default_tags on the AWS provider but they do not carry forward to the CloudWatch metric alarms created by the aws_appautoscaling_policy resource.

Note about tags from cloudwatch_metric_alarm documentation:
tags - (Optional) A map of tags to assign to the resource. If configured with a provider default_tags configuration block present, tags with matching keys will overwrite those defined at the provider-level.

Potential Terraform Configuration

resource "aws_appautoscaling_policy" "ecs_policy" {
  name               = "scale-down"
  policy_type        = "StepScaling"
  resource_id        = aws_appautoscaling_target.ecs_target.resource_id
  scalable_dimension = aws_appautoscaling_target.ecs_target.scalable_dimension
  service_namespace  = aws_appautoscaling_target.ecs_target.service_namespace

  step_scaling_policy_configuration {
    adjustment_type         = "ChangeInCapacity"
    cooldown                = 60
    metric_aggregation_type = "Maximum"

    step_adjustment {
      metric_interval_upper_bound = 0
      scaling_adjustment          = -1
    }
  }

  tags = var.common_tags
}
