[Form][Validator] Enable dynamic set of validation groups based on callback
Bug fix: no
Feature addition: yes
Backwards compatibility break: no
Symfony2 tests pass: yes
Symfony2 tests written for new feature: yes
closes tickets: #2498#1151
This will allow developer to pass a Closure or a callback array as a Validation groups option of a form. Eg:
```
class ClientType extends AbstarctType
{
// ...
public function getDefaultOptions(array $options)
{
return array(
'validation_groups' => function(FormInterface $form){
// return array of validation groups based on submitted user data (data is after transform)
$data = $form->getData();
if($data->getType() == Entity\Client::TYPE_PERSON)
return array('Default', 'person');
else
return array('Default', 'company');
},
);
}
// ...
}
```
```
class ClientType extends AbstarctType
{
// ...
public function getDefaultOptions(array $options)
{
return array(
'validation_groups' => array(
'Acme\\AcmeBundle\\Entity\\Client',
'determineValidationGroups'
),
);
}
// ...
}
```
This will make developers life easier !

Does that work if your ClientType were added to another form type?
e.g.
```php
<?php
class MyComplexType extends AbstractType
{
public function buildForm(FormBuilder $builder, array $options)
{
$builder->add('client', new ClientType());
}
// ...
}
```

This is doing nothing more than injecting array of validation groups, should work, but I have not tested this use case.

Now functionality is complete, test are written, and implementation is clean. :)

Can you add some tests for the `DelegatingValidator` class, which is where we can ensure that the new feature actually works as expected?

OK, I've written proof-of-concept tests, also I've squashed few commits to make things clear.
Personally I think this should go straight into 2.0 series, as it do not beak BC, and a feature is really nice to use.

@canni the 2.0 branch is for bug fixes, not for new features. This is the difference between maintenance releases and minor releases.
