 * The FeaturesExtensionStorages provides a collection of extension storages,

 * Typically this will include the install and optional directories defined by
 * Drupal core, but may also include any extension configuration directories
 * added by contributed modules.
 *
 * This class serves as a partial wrapper to
 * Drupal\Core\Config\StorageInterface, providing a subset of methods that can
 * be called to apply to all available extension storages. For example,
 * FeaturesExtensionStoragesInterface::read() will read an extension-provided
 * configuration item regardless of which extension storage directory it is
 * provided in.
