- 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)
