Trait to be used in Form models.

Adds two methods:

loadMultiple() to load multiple models
getModels() to get the loaded models

#Usage

class MyFormModel extends FormModel
{
    use Yiisoft\Form\LoadMultipleTrait;

    ...
}

In an action

    ....

    $form = new MyFormModel();

    if ($form->loadMultiple($request->getParsedBody())) {
        foreach ($form->getModels() as $i => $model) {
            if (!$validator->validate($model)
                ->isValid()) {
                throw new \Exception("Validation failed at $i");
            }
        }

        // persist the models and send response
    }
