This PR is about to check if the current user has one of the specified roles, example:

```php 
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Security;

class PostController extends Controller
{
    /**
     * @Security("has_any_roles(['ROLE_FOO', 'ROLE_BAR'])")
     */
    public function indexAction()
    {
        // ...
    }
}
```
