   * Base plugin manager for Bootstrap Layouts plugin managers.

   * The "container.namespaces" service does not contain theme namespaces
   * since themes are not registered in the container. To allow themes to be
   * able to participate in these plugins, the normal "namespaces" provided
   * must be appending with the missing autoloader prefixes of the themes.
   *
   * @param \Traversable $namespaces
   *   An object that implements \Traversable which contains the root paths
   *   keyed by the corresponding namespace to look for plugin implementations.
   * @param \Drupal\Core\Cache\CacheBackendInterface $cache_backend
   *   Cache backend instance to use.
   * @param \Drupal\Core\Extension\ModuleHandlerInterface $module_handler
   *   The module handler to invoke the alter hook with.
   * @param \Drupal\Core\Extension\ThemeHandlerInterface $theme_handler
   *   The theme manager used to invoke the alter hook with.
   * @param \Drupal\Core\Theme\ThemeManagerInterface $theme_manager
   *   The theme manager used to invoke the alter hook with.
   * @param string|null $plugin_interface
   *   (optional) The interface each plugin should implement.
   * @param string $plugin_definition_annotation_name
   *   (optional) The name of the annotation that contains the plugin definition.
   *   Defaults to 'Drupal\Component\Annotation\Plugin'.
