【概述】
1. 我们尝试做tpcc基准测试, 使用tiup bench tpcc run会遇到功能问题，有ERR：
[tpcc@gausssingapore2-0002 1000w]$ tiup bench tpcc run --max-procs 20 --warehouses 100 -T 20 --time 60s
Starting component `bench`: /home/tpcc/.tiup/components/bench/v1.5.1/tiup-bench tpcc run --max-procs 20 --warehouses 100 -T 20 --time 60s

2. 另一方面，尝试加上-H 和 -P 命令参数想远程对已做prepare的db进程运行，结果直接失败：
[tpcc@gausssingapore2-0002 ~]$ tiup bench tpcc run --max-procs 10 --warehouses 100 -T 10 --time 60s -H 192.168.0.60 -P 4000
