PubSub publish behaves differently with Redis in cluster mode about kvrocks HOT 5 OPEN

@jcy1001 Which client you're using?

from kvrocks.

@git-hulk I found redis7 has this code ，but kvrocks doesnot propagatetocluster

/* PUBLISH */
void publishCommand(client *c) {
if (server.sentinel_mode) {
sentinelPublishCommand(c);
return;
}

int receivers = pubsubPublishMessageAndPropagateToCluster(c->argv[1],c->argv[2],0);
if (!server.cluster_enabled)
    forceCommandPropagation(c,PROPAGATE_REPL);
addReplyLongLong(c,receivers);

}

是，在redis集群下面客户端可以收到通知， kvrocks下收不到通知，分析看了是redis集群模式下，有做cluster的扩散，kvrocks只能通知本shard下的客户端
