 * - `toCompatibleObjectAsConfigFileContent()`
 *      Convert this configuration to the compatible object as the content of
 *      config files. It converts the loaded parser and plugins to strings.
 *      `CLIEngine#getConfigForFile(filePath)` method uses this method.
 *
 * `ConfigArray#extractConfig(filePath)` creates a `ExtractedConfig` instance.
