A bit of refactoring of the logging implementation was done as well. This should make it clear which logging instance is being used throughout.

Example Output:

{"asctime": "2024-07-10 22:53:31,912", "name": "root", "levelname": "INFO", "message": "Verbose Logging Enabled...", "taskName": null}
{"asctime": "2024-07-10 22:53:31,914", "name": "root", "levelname": "INFO", "message": "Searching for a valid settings.conf file.", "taskName": null}
{"asctime": "2024-07-10 22:53:31,915", "name": "root", "levelname": "INFO", "message": "Settings.conf found.", "taskName": null}
{"asctime": "2024-07-10 22:53:31,915", "name": "root", "levelname": "ERROR", "message": "Error: Invalid Kandji Tenant, check your settings.conf or environment variables and try again.", "taskName": null}
