Horizon vs Redis Cluster - Docs not very clear about this subject

[geowrgetudor]

Hello.
Can it be added somewhere in the docs that Horizon doesn't support Redis Cluster? I believe it can go both ways, in the Redis Clusters and somewhere in the Horizon docs.
On top of that, it would be neat if maybe Redis facade would throw a specific exception when Horizon is installed and you are using a Redis cluster for queue... because it seems like Horizon messes up with the facade. Maybe this is intended, but it's really confusing.
