   * Installs the default configuration of a given extension.

   * name prefix. For example, the Node module provides the frontpage view as a
   * default configuration file:
   * core/modules/node/config/optional/views.view.frontpage.yml
   * When the Views module is installed after the Node module is already
   * enabled, the frontpage view will be installed.
   *
   * Additionally, the default configuration directory for the extension being
   * installed is searched to discover if it contains default configuration
   * that is owned by other enabled extensions. So, the frontpage view will also
   * be installed when the Node module is installed after Views.
   *
   * @param string $type
   *   The extension type; e.g., 'module' or 'theme'.
   * @param string $name
   *   The name of the module or theme to install default configuration for.
