Clean up consumers: replace polling with VoiceManager.play_source()

- cron.py: replace while-is_playing polling with VoiceManager.play_source()
- vclogs.py: replace while-is_playing polling with VoiceManager.play_source()
- stop.py: use VoiceManager.disconnect() instead of raw voice_client
- join.py: use VoiceManager.connect() instead of raw channel.connect()
- voice.py: add back join_by_channel_id() convenience method
- Tests: update for new VoiceManager method names and signatures
