Automatic worker to update scores

[AlexMog]

The goal is to work on a new way to enter scores during events.
Instead of relying on Moderators, use a new system based on automatic workers that will check and update the player's scores.

For this system, some processes are important:

• Imagine a way to manage external workers (API Tokens, API Endpoints, etc., take a look on CI workers of Gitlab as an example).
• Create workers for games, if they can work (using games API?), the important part is to be able to retrive scores in "realtime".

Moved from worker to a plugin if the game permits it (cf. Minecraft)
