Draft: Patch mget in Redis::Cluster for cross-slot safety and efficiency

Redis Cross Slot error redis crossslot keys in request don't hash to the same slot The error log means: The requested Key key is not hashed into the same slot The key space of the Redis cluster is divided into 16384 slots, and the maximum redis crossslot keys in request don''t hash to the same slot CROSSSLOT Keys in request don't hash to the same slot Solution 1 One solution is to force redis to insert the keys into same slot We can achieve
