Pass options to factories as creation options

[fabiang]

Currently it's not possible to pass creation options to factories registered at the FormElementManager, when form elements are created by the form factory.

I use factories a lot for creating form elements and atm it's only possible to pass creation options with (inside a Zend\Form\Form instance):

$this->add($this->factory->getFormElementManager()->get('some_type', [
    'some_option' => 'some_value'
]));

Imho options from create() should also be passed as creation options to the factories.

This PR makes it possible to short-cut the above to the following:

$this->add([
    'type' => 'some_type',
    'options' => [
        'some_option' => 'some_value',
    ]
]);

The registered factory for type some_type then just need to pass the creation options to the form element.

I'm going to cherry-pick this to master for the 2.7.1 release; I consider it a bug in current behavior.
