Title: Feature/redis pubsub set

Use a redis set for tracking subscribers to a Topic instead of an in-memory hash. This lets multiple processes subscribe to the same topic.

I suspect there's still some unresolved behavior around multiple topics and subscribers:

* there's no check to ensure uniquely named subscribers (if this is even an issue, as they're all Queues)
* there's no check to ensure multiple topics by the same name aren't stepping on each other, in particular when they're destroyed
