Allow use of all the RequestMatcher parameters by providing an array

Provider: Silex\Provider\SecurityServiceProvider
Little patch to make full use of the `RequestMatcher` in `$app['security.access_rules']`

```php
    $app['security.access_rules'] = [
        [[
            'host' => 'symfony.com',
            'ips' => '192.168.0.1',
            ...
         ], 'ROLE_ADMIN'],
        ...
    ];
```
