Robottelo setup on Python 3.12

[ogajduse]

This is a tracking issue for robottelo setup on Python 3.12

Release date for 3.12 is October 2nd 2023.

Blocking issues

• ssh2-python fails to build on 3.12: they will add 3.12 setup once 3.12 is released. Depends on Python 3.12 support ParallelSSH/ssh2-python#193
• cryptography does not install on 3.12: AttributeError: module 'pkgutil' has no attribute 'ImpImporter'. Did you mean: 'zipimporter'?
• unittest deprecations breaking robottelo unit tests - https://docs.python.org/3/whatsnew/3.12.html#id3

I think cryptography issue won't be blocking us anymore with 3.12
