What's Changed

• Support sharded pubsub commands by @mgravell @vandyvilla @atakavci @xli in #2887

Sharded pub/sub operations are where the pub/sub channels are distributed over a multi-node redis cluster using similar slot rules to keys; all such operations (for both "pub" and "sub") must be communicated to the correct node. This contrasts to regular/legacy pub/sub where you can "pub" or "sub" to any node, and the message is broadcast horizontally via all nodes in the cluster. To use sharded operations, use the RedisChannel.Sharded API when constructing channels. There is no concept of pattern-based sharded pub/sub.
