Support shard pub/sub

As far as I know, redis 7.0 provides a slightly improved pub/sub.

Accordingly, lettuce related commands have been implemented. Are there any plans to abstract this? 🤔

We might, but the underlying issue is to track changes in Redis Cluster topologies and adopt the message listener accordingly. Sending pub/sub messages to shards isn't complex.

@mp911de , Valkey-GLIDE handles the Redis cluster topology updates and resubscribe on such events. We can integrate it for support of sharded pub/sub.
