// This API operation is superseded by AttachTrafficSources , which can attach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
// AttachLoadBalancerTargetGroups . You can use both the original
// AttachLoadBalancerTargetGroups API operation and AttachTrafficSources on the
// same Auto Scaling group. Attaches one or more target groups to the specified
// Auto Scaling group. This operation is used with the following load balancer
// types:
//   - Application Load Balancer - Operates at the application layer (layer 7) and
//     supports HTTP and HTTPS.
//   - Network Load Balancer - Operates at the transport layer (layer 4) and
//     supports TCP, TLS, and UDP.
//   - Gateway Load Balancer - Operates at the network layer (layer 3).
//
// To describe the target groups for an Auto Scaling group, call the
// DescribeLoadBalancerTargetGroups API. To detach the target group from the Auto
// Scaling group, call the DetachLoadBalancerTargetGroups API. This operation is
// additive and does not detach existing target groups or Classic Load Balancers
// 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)
// in the Amazon EC2 Auto Scaling User Guide.
