[sinks/globallog] Globallog proper exit

[zangjiucheng]

Current the only way to exit globallog is by ctrl+c which may crash the log file we implement, we hope to develop a hotkey detect to proper exit the globallog.

For future reference

Use Case Breakdown

As a test site DAQ operator;
I would want to be able to ensure that globallog exits properly and that the log file is saved properly to disk;
Because, the logging data is critical for testing and currently the program does not exit cleanly and can even fail to respond to SIGINT

Requirements

• Globallog sink MUST close the file handle cleanly on SIGINT, SIGTERM, or any other scenario to prevent file corruption
• Globallog sink MUST display the hotkeys to interrupt logging to the user
