/**
 * <p>Gets a key group configuration.</p>
 *          <p>To get a key group configuration, you must provide the key group's identifier. If the
 * 			key group is referenced in a distribution's cache behavior, you can get the key group's
 * 			identifier using <code>ListDistributions</code> or <code>GetDistribution</code>. If the
 * 			key group is not referenced in a cache behavior, you can get the identifier using
 * 				<code>ListKeyGroups</code>.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { CloudFrontClient, GetKeyGroupConfigCommand } from "@aws-sdk/client-cloudfront"; // ES Modules import
 * // const { CloudFrontClient, GetKeyGroupConfigCommand } = require("@aws-sdk/client-cloudfront"); // CommonJS import
 * const client = new CloudFrontClient(config);
 * const input = { // GetKeyGroupConfigRequest
 *   Id: "STRING_VALUE", // required

 * const command = new GetKeyGroupConfigCommand(input);
 * const response = await client.send(command);
 * // { // GetKeyGroupConfigResult
 * //   KeyGroupConfig: { // KeyGroupConfig
 * //     Name: "STRING_VALUE", // required
