`api_queue` created - deprecate `website`, `postgres`, `redis`

[calaldees]

• Created new api_queue using python sanic.
• tracks queued now have an absolute start_time. There is no need for play/stop events. There is only a queue_updated event
• api_queue auto generate openapi documentation.
• new queue model is based on csv files that get asyncio locked.
• deprecate website, postgres, redis, mosquitto(auth) (code to be removed in later commit)

The api_queue is complete enough for testing/integrating into clients TODO: add extra validation to POST /queue/{name}/ for creating new queue items. e.g. event_end and duplicate_performer

curl commands are provided in /api_queue/README.md and documentation is available at http://localhost/docs

Talked this PR though with @shish . Looks like we're ready to try integrating this with the clients! Good luck!
