      '''Create a new autoscale rule - pass the output in a list to create_autoscale_setting().
  
      Args:
          subscription_id (str): Azure subscription id.
          resource_group (str): Azure resource group name.
          vmss_name (str): Name of scale set to apply scale events to.
          metric_name (str): Name of metric being evaluated.
          operator (str): Operator to evaluate. E.g. "GreaterThan".
          threshold (str): Threshold to trigger action.
          direction (str): Direction of action. E.g. Increase.
          change_count (str): How many to increase or decrease by.
          time_grain (str): Optional. Measurement granularity. Default 'PT1M'.
          time_window (str): Optional. Range of time to collect data over. Default 'PT5M'.
          cool_down (str): Optional. Time to wait after last scaling action. ISO 8601 format.
              Default 'PT1M'.
      Returns:
          HTTP response. JSON body of autoscale setting.
