Integration for fetching user music listening history

[oreHGA]

We already have a flow to:

• authenticate a user account and fetch recently played songs for a user

• process and return the features of songs a user is listening to

We should integrate an OAuth flow to the spotify api that allows us to fetch listening history for a user periodically and update:

• [ ] on the settings page, user connects account
• [ ] client sends token to the backend server to store in keystore
• [ ] adds a controller endpoint to periodically fetch from spotify on behalf of user
• [ ] call the upload api to store data for user

https://github.com/dgendill/spotify-play-history has a good javascript example for connecting to spoify api and fetching periodically.

Data should be stored in remote blob (if user consents) - /y/m/d/-listening_history.json

Fell off the wagon here but I'm back now, I'll make a PR later tonight with the backend pieces for this : https://developer.spotify.com/documentation/web-api/tutorials/code-flow
