As described in redis-benchamrk help message 'The test names are the same as the ones produced as output.', In redis-benchmark output, we can only see PING_BULK, but the cmd `redis-benchmark -t ping_bulk` is not supported. We have to run it with ping_mbulk which is not user friendly.
- add test suite coverage for redis-benchmark
- add --version (similar to what redis-cli has)
- fix bug sending more requests than intended when pipeline > 1.
- when done sending requests, avoid freeing client in the write handler, in theory before
responses are received (probably dead code since the read handler will call clientDone first)
