Ability to alter the Dropdown widget

With help of the MR !4, We can able to alter the results of the Entity select list.

/**
 * Implements hook_verf_entites_options_alter().
 */
function example_verf_entites_options_alter(&$referenceable_entities) {
  foreach ($referenceable_entities as $key => $entites) {
    if (!$entites->hasRole('administrator')) {
      unset($referenceable_entities[$key]);
    }
  }
}
