function FormTestController::storageLegacyHandler

Emulate legacy AHAH-style ajax callback.

Drupal 6 AHAH callbacks used to operate directly on forms retrieved using \Drupal::formBuilder()->getCache() and stored using \Drupal::formBuilder()->setCache() after manipulation. This callback helps testing whether \Drupal::formBuilder()->setCache() prevents resaving of immutable forms.
