/**
 * <p>Describes the available types of lifecycle hooks.</p>
 *          <p>The following hook types are supported:</p>
 *          <ul>
 *             <li>
 *                <p>
 *                   <code>autoscaling:EC2_INSTANCE_LAUNCHING</code>
 *                </p>
 *             </li>
 *             <li>
 *                <p>
 *                   <code>autoscaling:EC2_INSTANCE_TERMINATING</code>
 *                </p>
 *             </li>
 *          </ul>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { AutoScalingClient, DescribeLifecycleHookTypesCommand } from "@aws-sdk/client-auto-scaling"; // ES Modules import
 * // const { AutoScalingClient, DescribeLifecycleHookTypesCommand } = 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 = {};
 * const command = new DescribeLifecycleHookTypesCommand(input);
 * const response = await client.send(command);
 * // { // DescribeLifecycleHookTypesAnswer
 * //   LifecycleHookTypes: [ // AutoScalingNotificationTypes
 * //     "STRING_VALUE",
 * //   ],
 * // };
 *
 * ```
 *
 * @param DescribeLifecycleHookTypesCommandInput - {@link DescribeLifecycleHookTypesCommandInput}
 * @returns {@link DescribeLifecycleHookTypesCommandOutput}
 * @see {@link DescribeLifecycleHookTypesCommandInput} for command's `input` shape.
 * @see {@link DescribeLifecycleHookTypesCommandOutput} for command's `response` shape.
 * @see {@link AutoScalingClientResolvedConfig | config} for AutoScalingClient's `config` shape.
 *
 * @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 AutoScalingServiceException}
 * <p>Base exception class for all service exceptions from AutoScaling service.</p>
 *
 *
 * @example To describe the available types of lifecycle hooks
 * ```javascript
 * // This example describes the available lifecycle hook types.
 * const input = { /* empty *\/ };
 * const command = new DescribeLifecycleHookTypesCommand(input);
 * const response = await client.send(command);
 * /* response is
 * {
 *   LifecycleHookTypes: [
 *     "autoscaling:EC2_INSTANCE_LAUNCHING",
 *     "autoscaling:EC2_INSTANCE_TERMINATING"
 *   ]
 * }
 * *\/
