TLS client verification used to be accidentally disabled in libvirt.
This was fixed in libvirt-6.10.0-1.
Which means, once you're using libvirt-6.10.0-1 or higher, a client
certificate is mandatory during live migration with TLS.
If we simply create the client certificate, this will fix live-migration
of newly created instance but will not fix already created instances.
This change will allow us to keep client certificate validation disabled
during the train release cycle and re-enable it from Wallaby and onward.
