When using redis cluster, keys in lua script should be in the same slot. In current implementation, u use KEYS for lock_name, owner, expire. In most cases, they are not in the same slot, so it will raise rediscluster.exceptions.RedisClusterException: EVALSHA - all keys must map to the same key slot if use redis-py-cluster as backend.
I think it's more reasonable to use ARGV for owner and expire as they are actually not KEYS. And with ARGV, it will be compatible to redis cluster.
