support for python 3.12+ ?

[lsm5]

Filing this to get everyone's eyes just in case.

Looks like there was some recent python update on rawhide that broke a few python packages.

I don't know if it's a rawhide problem and if things will magically be resolved on the fedora side itself OR if we need any changes in podman-py but I'm currently unable to install python-podman from the podman-next copr on my local rawhide environment.

Also, setup.cfg upstream only mentions up to 3.11.

$ sudo dnf install python-podman

You can try to add to command line:
  --no-best to not limit the transaction to the best candidates
  --skip-broken to skip uninstallable packages

@inknos PTAL

Adding py312 to the envlist in the tox.ini file would be the first step to having that environment tested.

Most of the dependencies are allowed to float to the current defaults on each platform. @inknos knows about the issue with pyxdg not being supported and has solutions. The urllib3 and requests libraries are worrisome.
