Use of Deprecated PySNMP Listener

[thebeanogamer]

QwikContext

omsdk.sdksnmptrap uses pysnmp.carrier.asynsock, which will be removed in future pysnmp releases and does not work on Python 3.12.

Details

omsdk.sdksnmptrap and omsdk.sdktrapreceiver import pysnmp.carrier.asynsock. This will be removed from PySNMP soon (etingof/pysnmp@b186168) however this poses a more immediate problem for Python 3.12. Python 3.12 has removed support for asyncore entirely (python/cpython#96580), so it'd probably be best to switch to the asyncio support in PySNMP on Python 3.

Repro Steps

1. Install Python 3.12 (a Fedora Rawhide container is probably the fastest way).
2. pip install omsdk
3. Import omsdk.sdksnmptrap in a Python file.
