feat: player and map ranking ladder scores manager

[ahmadbky]

• Add a new player-map-ranking crate. It exposes a function to compute the leaderboard (ladder) of the players and maps, based on a certain formula per player record on a map.
• Add a new compute-player-map-ranking crate. It's a binary used to output the result of the above function to two separate CSV files.
• Add a new task running in the socc crate, that uses the new function, and output the result in two separate Redis ZSETs.
• Add a new managed environment variable, used by the above task, for the interval of the compute made by the socc crate. It defaults to 1 week.

Refs: #86.
