Name of the event fired when the export storage is used.

This event allows subscribers to modify the configuration which is about to be exported. The event listener method receives a \Drupal\Core\Config\StorageTransformEvent instance. This event contains a config storage which subscribers can interact with and which will finally be used to export the configuration from.

$storage = $event->getStorage();

Typically subscribers will want to perform the reverse operation on the storage than for \Drupal\Core\Config\ConfigEvents::STORAGE_TRANSFORM_IMPORT to make sure successive exports and imports yield no difference.
