// Gets information about the load balancers for the specified Auto Scaling group.
// This operation describes only Classic Load Balancers. If you have Application
// Load Balancers, Network Load Balancers, or Gateway Load Balancer, use the
// DescribeLoadBalancerTargetGroups API instead. To determine the attachment status
// of the load balancer, use the State element in the response. When you attach a
// load balancer to an Auto Scaling group, the initial State value is Adding. The
// state transitions to Added after all Auto Scaling instances are registered with
// the load balancer. If Elastic Load Balancing health checks are enabled for the
// Auto Scaling group, the state transitions to InService after at least one Auto
// Scaling instance passes the health check. When the load balancer is in the
// InService state, Amazon EC2 Auto Scaling can terminate and replace any instances
// that are reported as unhealthy. If no registered instances pass the health
// checks, the load balancer doesn't enter the InService state. Load balancers also
// have an InService state if you attach them in the CreateAutoScalingGroup API
// call. If your load balancer state is InService, but it is not working properly,
// check the scaling activities by calling DescribeScalingActivities and take any
// corrective actions necessary. For help with failed health checks, see
// Troubleshooting Amazon EC2 Auto Scaling: Health checks
// (https://docs.aws.amazon.com/autoscaling/ec2/userguide/ts-as-healthchecks.html)
// in the Amazon EC2 Auto Scaling User Guide. For more information, see Use Elastic
// Load Balancing to distribute traffic across the instances in your Auto Scaling
// group
