Product Opener/MongoDB indexes

⚠️ DEPRECATED: refer to openfoodfacts-server /conf/mongodb/create_indexes.js instead
https://github.com/openfoodfacts/openfoodfacts-server/blob/main/scripts/create_mongodb_indexes.pl
Note: the current indexes are probably not the best indexes, they are used on the current Open Food Facts production server and are thus "good enough", but they certainly can - and should - be improved.
In addition, some indexes are probably not used anymore and should be removed.
Help to create better indexes is much welcome! :-)
