Utility for calculating slot + node for a key in a OSS Cluster

Redis CLUSTER SLOTS redis slot CLUSTER GETKEYSINSLOT The command returns an array of keys names stored in the contacted node and hashing to the specified hash slot The maximum number of redis crossslot keys in request don''t hash to the same slot But in this example we'll assume they are just ten, from 0 to 9 ;) Different nodes will hold a subset of hash slots A given key foo is at slot: slot = crc16
