[kernel/command] don't print int as string in toString() method
[benchmark] update version

ChangeLog:
- 930e33305fbbf0ac9c5072b72a95c86d0a81ad6c
  Test also HDEL, ATGET, ATSET, ATDEL commands
[utils/one_conn_awk_bench] decrease LIMIT to 100000 (was 1000000)

Too slow
[utils/run_tests] add new script that run all tests

Before this patch all tests was registed in .travis.yml,
it is not so good, because you can't run it manually, so I add wrapper
for this.
[utils/run_tests] add test with random keys.
