 * A helper class to determine if a plugin is configurable.

 * Because configurable plugins in Drupal 8 might implement either the
 * deprecated ConfigurablePluginInterface or the new ConfigurableInterface,

 * plugin is configurable without checking it against a deprecated interface.
 * In Drupal 9, this check should be reduced to checking for
 * ConfigurableInterface only and be deprecated in favor of calling classes
 * checking against the interface directly.
