 * Provides access to default configuration for locale integration.

 * - Required default configuration (config/install/*)
 * - Optional default configuration (config/optional/*)
 * - Predefined languages mocked as default configuration (list defined in
 *   LocaleConfigManagerInterface::getStandardLanguageList())
 *
 * These sources are considered equal in terms of how locale module interacts
 * with them for translation. Their translatable source strings are exposed
 * for interface translation and participate in remote translation updates.
