Caleb Johnson 8e6db0829c [Audio] Connect to lavalink in the background (#2460)
Also:
- restart and reconnect if connection settings change
  - shutdown and restart if not configured to use external
- show a message in [p]play et al. when the connection hasn't been made
- move the JAR download to manager so audio.py can access it
- only start if no process exists
- bump red-lavalink to 0.2.3

Resolves #2306
