Draft: No story: wf_monitor improvements

Why This Is a Draft

Note: this MR is a draft until both WS-2898 (writing tests for wf_monitor) and WS-3215 (Set up SonarQube for code analysis) are done and the analysis done using the SonarQube setup from WS-3215 is done.

Work Description

This involved:

• Making sure wf_monitor passed the default Pylint and SonarLint checks.
• Ensuring all methods and functions have accurate docstrings.

Note: the "us-ascii" encoding was found from running "file -i" on a condor log from Workspaces on dev and getting the charset value. The file I used was in /lustre/aoc/cluster/pipeline/dsoc-dev/workspaces/spool/tmpjsesjhoq, which is a calibration that was done on 12/27.

Also, in monitor.htc_log_process_end_of_event_line and monitor.dag_log_process_end_of_event_line, should_continue and should_break variables were used in and passed back to the callers to ensure the same loop behavior as before the code was modified.
