* [x] STDIN for subprocess and SSH
* [x] `execute_async` has universal API
* [x] `execute`, `check_call` and `check_output` are shared
* [x] command can be masked for logs
* [x] all commands have default timeout instead of infinite wait
* [x] non-block subprocess pipe pull (including windows)

* Code-style: now 120 symbols/line
