/**
 * <note>
 *             <p>This API operation is superseded by <a href="https://docs.aws.amazon.com/autoscaling/ec2/APIReference/API_AttachTrafficSources.html">AttachTrafficSources</a>, which
 *                 can attach multiple traffic sources types. We recommend using
 *                 <code>AttachTrafficSources</code> to simplify how you manage traffic sources.
 *                 However, we continue to support <code>AttachLoadBalancers</code>. You can use both
 *                 the original <code>AttachLoadBalancers</code> API operation and
 *                     <code>AttachTrafficSources</code> on the same Auto Scaling group.</p>
 *          </note>
 *          <p>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.</p>
 *          <p>To describe the load balancers for an Auto Scaling group, call the <a href="https://docs.aws.amazon.com/autoscaling/ec2/APIReference/API_DescribeLoadBalancers.html">DescribeLoadBalancers</a> API.
 *             To detach a load balancer from the Auto Scaling group, call the <a href="https://docs.aws.amazon.com/autoscaling/ec2/APIReference/API_DetachLoadBalancers.html">DetachLoadBalancers</a>
 *             API.</p>
 *          <p>This operation is additive and does not detach existing Classic Load Balancers or
 *             target groups from the Auto Scaling group.</p>
 *          <p>For more information, see <a href="https://docs.aws.amazon.com/autoscaling/ec2/userguide/autoscaling-load-balancer.html">Use Elastic Load Balancing to
 *                 distribute traffic across the instances in your Auto Scaling group</a> in the
 *                 <i>Amazon EC2 Auto Scaling User Guide</i>.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { AutoScalingClient, AttachLoadBalancersCommand } from "@aws-sdk/client-auto-scaling"; // ES Modules import
 * // const { AutoScalingClient, AttachLoadBalancersCommand } = require("@aws-sdk/client-auto-scaling"); // CommonJS import
 * // import type { AutoScalingClientConfig } from "@aws-sdk/client-auto-scaling";
 * const config = {}; // type is AutoScalingClientConfig
 * const client = new AutoScalingClient(config);
 * const input = { // AttachLoadBalancersType
 *   AutoScalingGroupName: "STRING_VALUE", // required
 *   LoadBalancerNames: [ // LoadBalancerNames // required
 *     "STRING_VALUE",
 *   ],
 * };
 * const command = new AttachLoadBalancersCommand(input);
 * const response = await client.send(command);
 * // {};
 *
 * ```
 *
 * @param AttachLoadBalancersCommandInput - {@link AttachLoadBalancersCommandInput}
 * @returns {@link AttachLoadBalancersCommandOutput}
 * @see {@link AttachLoadBalancersCommandInput} for command's `input` shape.
 * @see {@link AttachLoadBalancersCommandOutput} for command's `response` shape.
 * @see {@link AutoScalingClientResolvedConfig | config} for AutoScalingClient's `config` shape.
 *
 * @throws {@link InstanceRefreshInProgressFault} (client fault)
 *  <p>The request failed because an active instance refresh already exists for the specified
 *             Auto Scaling group.</p>
 *
 * @throws {@link ResourceContentionFault} (server fault)
 *  <p>You already have a pending update to an Amazon EC2 Auto Scaling resource (for example, an Auto Scaling group,
 *             instance, or load balancer).</p>
 *
 * @throws {@link ServiceLinkedRoleFailure} (server fault)
 *  <p>The service-linked role is not yet ready for use.</p>
 *
 * @throws {@link AutoScalingServiceException}
 * <p>Base exception class for all service exceptions from AutoScaling service.</p>
 *
 *
 * @example To attach a load balancer to an Auto Scaling group
 * ```javascript
 * // This example attaches the specified load balancer to the specified Auto Scaling group.
 * const input = {
 *   AutoScalingGroupName: "my-auto-scaling-group",
 *   LoadBalancerNames: [
 *     "my-load-balancer"
 *   ]
 * };
 * const command = new AttachLoadBalancersCommand(input);
 * const response = await client.send(command);
