I've made a dirty one: https://gerrit.ovirt.org/98150 (you can simply cherry pick the to wherever you need). However, it doesn't work, it's still built with Python 2 on my Fedora 28. I can see a lot of warning such as DEPRECATION WARNING: python2 invoked with /usr/bin/python. Use /usr/bin/python3 or /usr/bin/python2 /usr/bin/python will be removed or switched to Python 3 in the future. I can see that configure.ac in your patches still uses Python 2. Here is what I used in my private hacks to change that. Something similar should be done, depending on --enable-python3-build presence, and with properly detected Python versions.
