Rewrites the lunars server, changing several key components and implementing a new rating system

Key server changes:

Switch from nickel to rocket as the http server framework
Switch from rusqlite to sqlx as the database framework
Switch from sqlite to MySql server as the database
Automatically generate documentation (openapi.json) based off routes and schema
Implement ratelimiting as a 1 minute sliding window, where unauthenticated users can send up to 60 requests per minute and users with an api key can send up to 120 requests per minute
Change how authentication works; instead of passing a key inside a schema, the server will look for a key inside the Authorization header
Re-do the api, due to the fundamental change of the rating system

Rating system changes:

Switch from an ELO based system to a Glicko-2 based system (transfer the changes for ping compensation, match score)
The new glicko based system works with rating periods; we keep track of matches for a set period of time, and once the period has ended, we process the rating for all players
I have temporarily set the rating period length to 3 weeks. The specification mentions an ideal length would mean 5-10 matches played per player; we will see if 3 weeks works for that metric
To fix the UX of not being able to see your rating until the rating period is over, use the fractional rating period modification seen in the instant-glicko-2 crate

(Later today I will fully deploy the new version and generate api keys)
