/**
 * <p>Attaches one or more traffic sources to the specified Auto Scaling group.</p>
 *          <p>You can use any of the following as traffic sources for an Auto Scaling group:</p>
 *          <ul>
 *             <li>
 *                <p>Application Load Balancer</p>
 *             </li>
 *             <li>
 *                <p>Classic Load Balancer</p>
 *             </li>
 *             <li>
 *                <p>Gateway Load Balancer</p>
 *             </li>
 *             <li>
 *                <p>Network Load Balancer</p>
 *             </li>
 *             <li>
 *                <p>VPC Lattice</p>
 *             </li>
 *          </ul>
 *          <p>This operation is additive and does not detach existing traffic sources from the Auto Scaling
 *             group. </p>
 *          <p>After the operation completes, use the <a href="https://docs.aws.amazon.com/autoscaling/ec2/APIReference/API_DescribeTrafficSources.html">DescribeTrafficSources</a> API to
 *             return details about the state of the attachments between traffic sources and your Auto Scaling
 *             group. To detach a traffic source from the Auto Scaling group, call the
 *             <a href="https://docs.aws.amazon.com/autoscaling/ec2/APIReference/API_DetachTrafficSources.html">DetachTrafficSources</a> API.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { AutoScalingClient, AttachTrafficSourcesCommand } from "@aws-sdk/client-auto-scaling"; // ES Modules import
 * // const { AutoScalingClient, AttachTrafficSourcesCommand } = 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 = { // AttachTrafficSourcesType
 *   AutoScalingGroupName: "STRING_VALUE", // required
 *   TrafficSources: [ // TrafficSources // required
 *     { // TrafficSourceIdentifier
 *       Identifier: "STRING_VALUE", // required
 *       Type: "STRING_VALUE",
 *     },
 *   ],
 *   SkipZonalShiftValidation: true || false,
 * };
 * const command = new AttachTrafficSourcesCommand(input);
 * const response = await client.send(command);
 * // {};
 *
 * ```
 *
 * @param AttachTrafficSourcesCommandInput - {@link AttachTrafficSourcesCommandInput}
 * @returns {@link AttachTrafficSourcesCommandOutput}
 * @see {@link AttachTrafficSourcesCommandInput} for command's `input` shape.
 * @see {@link AttachTrafficSourcesCommandOutput} 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 target group to an Auto Scaling group
 * ```javascript
 * // This example attaches the specified target group to the specified Auto Scaling group.
 * const input = {
 *   AutoScalingGroupName: "my-auto-scaling-group",
 *   TrafficSources: [
 *     {
 *       Identifier: "arn:aws:elasticloadbalancing:us-west-2:123456789012:targetgroup/my-targets/73e2d6bc24d8a067"
