Wikidata max fetch frequency not handled

[ChristianFN2]

When using gatling, I realized about this bottleneck: Wikidata has a limit in fetching frequency which is reached with approximately 300 concurrent users in our application, which is not probable to happen, but should be handled regardless.

One possible solution in the future would be making periodic fetches to new questions and storing them in our database instead of generating them at game time.
