Python SyntaxWarning messages from regular expressions

[RobertCElliott]

The Python interpreter now expects an r prefix around strings that contain regular expression special characters, so some of the programs are now noisy.

$ fence_redfish --help
/usr/share/fence/fencing.py:617: SyntaxWarning: invalid escape sequence '\.'
  docs["longdesc"] = re.sub("\\\\f[BPIR]|\.P|\.TP|\.br\n", "", docs["longdesc"])
/usr/share/fence/fencing.py:652: SyntaxWarning: invalid escape sequence '\s'
  shortdesc = re.sub(".*\s\s+", "", opt["help"][31:])
/usr/share/fence/fencing.py:1275: SyntaxWarning: invalid escape sequence '\s'
  os.environ.update(line.partition('=')[::2] for line in output.decode("utf-8").split('\0') if not re.match("^\s*$", line))
Usage:
        fence_redfish [options]

Which python version is giving these errors?

The history for handling this language change is apparently:

• Python 3.6: DeprecationWarning (only printed if extra warnings are enabled)
• Python 3.12: SyntaxWarning (printed by default)

Fedora 39 has Python 3.12.2.
