* Refine wmill client.py `run_script_sync` and `run_script_by_path_sync` with more features
This commit enriches the functionality of the `run_script_sync` and `run_script_by_path_sync` functions. New features introduced include script cancellation upon exit, logging capabilities,
and script execution timeout. These enhancements improve script execution control and provide better debug information. The `get_result` function was also adjusted to enable the control
of 'is not None' assertion on the job result. Consequently, user flexibility is enhanced, and the method can cater to cases where a `None` result is within the expected behavior.
* remove unnecessary local import and rename cancel_atexit to cleanup
