pScheduler with Python 3.11

[laeti-tia]

Running pScheduler on Debian 12 which has Python 3.11 I see the following errors:

Performing basic troubleshooting of 2a2501b2df8f.

Everything listed here has been corrected. I'm probably going to start going through the Python code with PyLint and some other utilities to find things that are deprecated.
