/**
 * <p>Adds the specified Availability Zones to the set of Availability Zones for the specified load balancer
 *             in EC2-Classic or a default VPC.</p>
 *         <p>For load balancers in a non-default VPC, use <a>AttachLoadBalancerToSubnets</a>.</p>
 *         <p>The load balancer evenly distributes requests across all its registered Availability Zones
 *             that contain instances. For more information, see <a href="https://docs.aws.amazon.com/elasticloadbalancing/latest/classic/enable-disable-az.html">Add or Remove Availability Zones</a>
 *             in the <i>Classic Load Balancers Guide</i>.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { ElasticLoadBalancingClient, EnableAvailabilityZonesForLoadBalancerCommand } from "@aws-sdk/client-elastic-load-balancing"; // ES Modules import
 * // const { ElasticLoadBalancingClient, EnableAvailabilityZonesForLoadBalancerCommand } = require("@aws-sdk/client-elastic-load-balancing"); // CommonJS import
 * // import type { ElasticLoadBalancingClientConfig } from "@aws-sdk/client-elastic-load-balancing";
 * const config = {}; // type is ElasticLoadBalancingClientConfig
 * const client = new ElasticLoadBalancingClient(config);
 * const input = { // AddAvailabilityZonesInput
 *   LoadBalancerName: "STRING_VALUE", // required
 *   AvailabilityZones: [ // AvailabilityZones // required
 *     "STRING_VALUE",
 *   ],
 * };
 * const command = new EnableAvailabilityZonesForLoadBalancerCommand(input);
 * const response = await client.send(command);
 * // { // AddAvailabilityZonesOutput
 * //   AvailabilityZones: [ // AvailabilityZones
 * //     "STRING_VALUE",
 * //   ],
 * // };
 *
 * ```
 *
 * @param EnableAvailabilityZonesForLoadBalancerCommandInput - {@link EnableAvailabilityZonesForLoadBalancerCommandInput}
 * @returns {@link EnableAvailabilityZonesForLoadBalancerCommandOutput}
 * @see {@link EnableAvailabilityZonesForLoadBalancerCommandInput} for command's `input` shape.
 * @see {@link EnableAvailabilityZonesForLoadBalancerCommandOutput} for command's `response` shape.
 * @see {@link ElasticLoadBalancingClientResolvedConfig | config} for ElasticLoadBalancingClient's `config` shape.
 *
 * @throws {@link AccessPointNotFoundException} (client fault)
 *  <p>The specified load balancer does not exist.</p>
 *
 * @throws {@link ElasticLoadBalancingServiceException}

 * ```javascript
 * // This example adds the specified Availability Zone to the specified load balancer.
 * const input = {
 *   AvailabilityZones: [
 *     "us-west-2b"
 *   ],
