Separating the backends #88
Description
We have a few now.
- Dev
- Redis
- Legacy Redis
- Postgres (requested)
- NATS (requested)
- LavinMQ (reqeuested)
At this point, I think we should remove all backends from Cable, then make them each a separate shard. You include cable and the backend you want with it. Then other people could create new backends later. To do this, I think there's a few bits in #79 that could be abstracted out first.
