/**
 * <p>Modify the instance metadata parameters on a running or stopped instance. When you
 *             modify the parameters on a stopped instance, they are applied when the instance is
 *             started. When you modify the parameters on a running instance, the API responds with a
 *             state of “pending”. After the parameter modifications are successfully applied to the
 *             instance, the state of the modifications changes from “pending” to “applied” in
 *             subsequent describe-instances API calls. For more information, see <a href="https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-metadata.html">Instance metadata and user data</a> in the
 *                 <i>Amazon EC2 User Guide</i>.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { EC2Client, ModifyInstanceMetadataOptionsCommand } from "@aws-sdk/client-ec2"; // ES Modules import
 * // const { EC2Client, ModifyInstanceMetadataOptionsCommand } = require("@aws-sdk/client-ec2"); // CommonJS import
 * // import type { EC2ClientConfig } from "@aws-sdk/client-ec2";
 * const config = {}; // type is EC2ClientConfig
 * const client = new EC2Client(config);
 * const input = { // ModifyInstanceMetadataOptionsRequest
 *   InstanceId: "STRING_VALUE", // required
 *   HttpTokens: "optional" || "required",
 *   HttpPutResponseHopLimit: Number("int"),
 *   HttpEndpoint: "disabled" || "enabled",
 *   DryRun: true || false,
 *   HttpProtocolIpv6: "disabled" || "enabled",
 *   InstanceMetadataTags: "disabled" || "enabled",
 * };
 * const command = new ModifyInstanceMetadataOptionsCommand(input);
 * const response = await client.send(command);
 * // { // ModifyInstanceMetadataOptionsResult
 * //   InstanceId: "STRING_VALUE",
 * //   InstanceMetadataOptions: { // InstanceMetadataOptionsResponse
 * //     State: "pending" || "applied",
