// Specify the load-based auto scaling configuration for a specified layer. For
// more information, see Managing Load with Time-based and Load-based Instances
// (https://docs.aws.amazon.com/opsworks/latest/userguide/workinginstances-autoscaling.html).
// To use load-based auto scaling, you must create a set of load-based auto scaling
// instances. Load-based auto scaling operates only on the instances from that set,
// so you must ensure that you have created enough instances to handle the maximum
// anticipated load. Required Permissions: To use this action, an IAM user must
// have a Manage permissions level for the stack, or an attached policy that
// explicitly grants permissions. For more information on user permissions, see
// Managing User Permissions
// (https://docs.aws.amazon.com/opsworks/latest/userguide/opsworks-security-users.html).
