Autocompletion for options in the form type

[stof]

When writing a form type, it would be great to have autocompletion for keys of $options in the different methods where it is available.

These key should take into account the configuration of the form type itself (by looking at the code of its setDefaultOptions method and of all of its parent in the hierarchy (getParent and recursively, plus all form extensions applied at any level).
Thus, it is even possible to provide autocompletion for the type of the values in case addAllowedTypes or setAllowedTypes are used for some options: http://symfony.com/doc/current/components/options_resolver.html#configure-allowed-types

we already have key completion for extension, type and parent lookup:

Symfony\Component\OptionsResolver\OptionsResolverInterface::setDefaults
Symfony\Component\Form\FormTypeInterface::setDefaultOptions
Symfony\Component\Form\FormTypeInterface::buildForm
Symfony\Component\Form\FormBuilderInterface::add

missed some more?:

Symfony\Component\Form\FormBuilderInterface::create
Symfony\Component\OptionsResolver\OptionsResolverInterface::replaceDefaults

Well, the autocompletion of keys inside $options does not seem to work inside buildForm or buildView

[stof]

Note that I'm not talking of autcompletion for arguments when calling buildForm. I'm talking of the autocompletion of keys inside the form type method when using the $options argument
