SysLogHandler: Exception ignored in atexit callback

[lucmurer]

When the syslog server is not resolvable (see #72) there is an exception originated in the python standard-Library:

Exception ignored in atexit callback: <function shutdown at 0x7f39db663eb0>
Traceback (most recent call last):
  File "/usr/lib64/python3.10/logging/__init__.py", line 2183, in shutdown
    h.close()
  File "/usr/lib64/python3.10/logging/handlers.py", line 945, in close
    self.socket.close()
AttributeError: 'SysLogHandler' object has no attribute 'socket'

How to reproduce:

• Configure a SysLog server that has a non-resolvable hostname/fqdn
• Run some fotoobo command (for example fotoobo fgt get version)

This seems to be an upstream issue:

• First reported here, but closed now: SysLogHandler crash atexit python/cpython#82961
• But it seems it raised again with this: Fix for bug 30378 regressed SysLogHandler by making it resolve addresses at initialization instead of in .emit() python/cpython#82535

Probably the latter will solve the imminent effect, but not the base problem. Perhaps we need to fix this upstream.
