[PATCH 01/14] python: Replace asyncio.get_event_loop for Python 3.14

["Daniel P. Berrangé" <berrange@redhat.com>]

From: Richard W.M. Jones <rjones@redhat.com>

In Python 3.14, no asyncio event loop gets generated automatically.
Instead create one when we need it.  This should work with Python 3.13
as well.  This change was suggested here:

https://bugzilla.redhat.com/show_bug.cgi?id=2375004#c4

See-also: https://docs.python.org/3.14/whatsnew/3.14.html#id7
Thanks: Miro Hrončok, Daniel P. Berrangé
