/**
 *
 *
 * Auto Scaling is a web service designed to automatically launch or terminate EC2 instances based on user-defined policies, schedules, and
 * health checks. Auto Scaling responds automatically to changing conditions. All you need to do is specify how it should respond to those
 * changes.
 *
 * Auto Scaling groups can work across multiple Availability Zones - distinct physical locations for the hosted Amazon EC2 instances - so that
 * if an Availability Zone becomes unavailable, Auto Scaling will automatically redistribute applications to a different Availability Zone.
 *
 * Every API call returns a response meta data object that contains a request identifier. Successful requests return an HTTP 200 status code.
 * Unsuccessful requests return an error object and an HTTP status code of 400 or 500.

	 *
	 * Adjusts the desired size of the AutoScalingGroup by initiating scaling activities. When reducing the size of the group, it is not possible
	 * to define which EC2 instances will be terminated. This applies to any auto-scaling decisions that might result in terminating instances.
	 *
	 * There are two common use cases for <code>SetDesiredCapacity</code>: one for users of the Auto Scaling triggering system, and another for
	 * developers who write their own triggering systems. Both use cases relate to the concept of cooldown.
	 *
	 * In the first case, if you use the Auto Scaling triggering system, <code>SetDesiredCapacity</code> changes the size of your Auto Scaling
	 * group without regard to the cooldown period. This could be useful, for example, if Auto Scaling did something unexpected for some reason. If
	 * your cooldown period is 10 minutes, Auto Scaling would normally reject requests to change the size of the group for that entire 10 minute
	 * period. The <code>SetDesiredCapacity</code> command allows you to circumvent this restriction and change the size of the group before the
	 * end of the cooldown period.
	 *
	 * In the second case, if you write your own triggering system, you can use <code>SetDesiredCapacity</code> to control the size of your Auto
	 * Scaling group. If you want the same cooldown functionality that Auto Scaling offers, you can configure <code>SetDesiredCapacity</code> to
	 * honor cooldown by setting the <code>HonorCooldown</code> parameter to <code>true</code>.
	 *
	 * @param string $auto_scaling_group_name (Required) The name of the AutoScalingGroup.

	 * 	<li><code>HonorCooldown</code> - <code>boolean</code> - Optional - By default, <code>SetDesiredCapacity</code> overrides any cooldown period. Set to True if you want Auto Scaling to reject this request if the Auto Scaling group is in cooldown. </li>
