python-prometheus_client fails to build with Python 3.11.0a4.

==================================== ERRORS ====================================
_____________________ ERROR collecting tests/test_core.py ______________________
ImportError while importing test module '/builddir/build/BUILD/client_python-0.13.1/tests/test_core.py'.
Hint: make sure your test modules/packages have valid Python names.
Traceback:
/usr/lib64/python3.11/importlib/__init__.py:126: in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
tests/test_core.py:13: in <module>
    from inspect import getargspec
E   ImportError: cannot import name 'getargspec' from 'inspect' (/usr/lib64/python3.11/inspect.py)

Removed from the inspect module:
    the getargspec function, deprecated since Python 3.0; use inspect.signature() or inspect.getfullargspec() instead.
    the formatargspec function, deprecated since Python 3.5; use the inspect.signature() function and Signature object directly.
    the undocumented Signature.from_builtin and Signature.from_function functions, deprecated since Python 3.5; use the Signature.from_callable() method instead.

Testing and mass rebuild of packages is happening in copr. You can follow these instructions to test locally in mock if your package builds with Python 3.11:

Let us know here if you have any questions.

Python 3.11 is planned to be included in Fedora 37. To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.11.
A build failure prevents us from testing all dependent packages (transitive [Build]Requires), so if this package is required a lot, it's important for us to get it fixed soon.
We'd appreciate help from the people who know this package best, but if you don't want to work on this now, let us know so we can try to work around it on our side.
