feat: openfoodfacts#2339 - added language and country to query produc…

…t list keys

What:
* added language and country to query product list keys
* that means that if I run a query for "pizza", not only the results will be different depending on the language and country (that was already the case), but the results will be cached accordingly - if I change language or country, I will see the cached results for those new language/country, not the results of the same query but with different language/country
* we needed that improvement in order to display correctly the "world" results; that was the first step
* also moved all the "query" classes to a specific folder
* fun fact: there are more "pizza"s in France than in Italy
