feat(database): setup initial vitess configurations

[ihatelactose]

Description 🎯

Vitess is a scalable cloud-native database layer that internally uses MySQL as database. However the layer created by Vitess makes MySQL sharding easier to do and use. It also manages the entire part of sharding and stuff. Which also means that this exposes only one mysql instance, therefore your application thinks its just talking to one mysqld instance!
