// This API operation is superseded by AttachTrafficSources , which can attach
// multiple traffic sources types. We recommend using AttachTrafficSources to
// simplify how you manage traffic sources. However, we continue to support
// AttachLoadBalancers . You can use both the original AttachLoadBalancers API
// operation and AttachTrafficSources on the same Auto Scaling group. Attaches one
// or more Classic Load Balancers to the specified Auto Scaling group. Amazon EC2
// Auto Scaling registers the running instances with these Classic Load Balancers.
// To describe the load balancers for an Auto Scaling group, call the
// DescribeLoadBalancers API. To detach a load balancer from the Auto Scaling
// group, call the DetachLoadBalancers API. This operation is additive and does
// not detach existing Classic Load Balancers or target groups from the Auto
// Scaling group. For more information, see Use Elastic Load Balancing to
// distribute traffic across the instances in your Auto Scaling group (https://docs.aws.amazon.com/autoscaling/ec2/userguide/autoscaling-load-balancer.html)
