In Drupal 7, you can set the default export path for the [features](https://www.drupal.org/project/features) module by setting the variable 'features_default_export_path':

    variable_set('features_default_export_path', 'sites/all/modules/custom/features');

What is the equivalent in Drupal 8? Can the export path be set in the features.settings configuration object?
