Add backend for settings screen

[evan10s]

We need a place to store settings and other information required to upload data. This might include:

• YouTube credentials such as client_secrets.json (maybe just store the location of the file)
• The event name
• TBA event code
• The description template file (maybe use mustache or handlebars?)
• other info we want to include in the video description:
  • social media handles
  • custom text

Overall flow:

• Pick a file format to store settings on disk
  • JSON is probably easiest
• Create said file manually with some sample data
• Add a file in repos as well as a service in services. The repo should allow reading/writing a key-value pair to the file directly. The service should call the repo function to read/write settings, without caring about how that happens.
  • Include a TypeScript interface detailing the available settings (the type should probably go in the models directory but I don't think we need a whole class here, just an interface.
• Add an API endpoint that allows updating the settings, using the previously created service.
• Add an API endpoint to read settings, again using the service. It is probably fine to return all the settings at once and let consumers parse into it.
