Rafael dos Santos Silva 315a38e0e3 FEATURE: Allow running message_bus in a different redis instance (#7616)
Adds `DISCOURSE_MESSAGE_BUS_REDIS_ENABLED` env var, that when set
to true, will allow Discourse to connect to a different redis
instance for MessageBus needs.

When enabled you can configure the same env vars user for redis,
but prefixed by `MESSAGE_BUS`, eg:

`DISCOURSE_MESSAGE_BUS_REDIS_HOST`
