[ToDo] add models for MongoDB

[gbowne1]

To be effective as a full stack client and server/backend/database application using MongoDB it will need collections and models useful for a Twitch bot.

The leaderboard will need collections to use in the metrics displaying on the leaderboard like messages sent, commands used and whatever things the Twitch API and tmi.js will let us track when its connected to twitch.

The login will need a database to track the bot users authorization and access and authentication etc.

The database should be called 'twitchbot' and the easiest method is to use mongosh and mongod together as the mongodb client and server.

Models, schemas, etc should be placed in a /models folder/directory L
