[Version 2 Release] resource/aws_appautoscaling_policy: Remove deprecated arguments

[bflad]

Description

Tracking issue for https://www.terraform.io/docs/providers/aws/guides/version-2-upgrade.html#resource-aws_appautoscaling_policy

Argument Removals

The following arguments have been moved into a nested argument named step_scaling_policy_configuration:

• adjustment_type
• cooldown
• metric_aggregation_type
• min_adjustment_magnitude
• step_adjustment

For example, given this previous configuration:

resource "aws_appautoscaling_policy" "example" {
  # ... other configuration ...

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

  step_adjustment {
    metric_interval_upper_bound = 0
    scaling_adjustment          = -1
  }
}

An updated configuration:

resource "aws_appautoscaling_policy" "example" {
  # ... other configuration ...

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

    step_adjustment {
      metric_interval_upper_bound = 0
      scaling_adjustment          = -1
    }
  }
}
