[ironic] [requirements] broken libvirt-python on yoga on stream 9

Hi all,

It is happening again, the Bifrost CI is broken because libvirt-python cannot be built from source, this time on Stream 9.

Missing type converters: int *:1 ERROR: failed virDomainQemuMonitorCommandWithFiles

I created a gist with a reproducer: https://gist.github.com/dtantsur/835303c6a68ed77157016f5955183115.

I cannot count how many times we had to deal with similar errors. I assume, libvirt-python has to be newer than the installed Python (8.2.0 in CS9, 8.0.0 in constraints). Should we stop constraining libvirt-python? Any other ideas?
