Pawel plesniak/pm logs

Defining a logger for the pm in the base class. Tested to be working with unified-shell and process-manager-shell.

Note - I wanted to plug this into update_log_level but I think there may be a problem with the hierarchy of the loggers - I could not show a RichHanlder instance after running update_log_level, creating a logger, and dumping its handlers even if using a name following the update_log_level logger as e.g. drunc.process_manager

Also what is the difference between self.log and self._log?

This now creates a log file for the ProcessManager. There is some cleanup that needs to happen with logging, which will be addressed in a seperate PR, namely

• having loggers inherit the root logger handler properties, by calling all loggers drunc.<logger_name>
• removing console print and having everything be contained in the logs instead
• removing print_traceback for the processes that are not viewed through a tty and replacing this with sys.exception
