Title: fix #2036 define config keys to allow override

Looks like 'controller' and 'sylius' keys have to be explicitly declared, otherwise the merged config would look like:

```
{
"defaults": {
"1": {
"template": "AcmeBundle:Product:indexByCategorySlug.html.twig"
},
"0": "AcmeBundle:Product:indexByCategorySlug",
"sylius": {
"template": "SyliusWebBundle:Frontend\\/Product:indexByTaxon.html.twig"
},
"controller": "sylius.controller.product:indexByTaxonAction"
},
"prefix": "\\/t",
"field": "permalink"
}
```
