Upper constraints were updated [1] to allow libvirt-python 7.5.0. The
first Kayobe builds using this version worked fine, but later they
started failing with the error:
The `libvirt` module is not importable. Check the requirements.
The main difference is that successful jobs were using the source
archive libvirt-python-7.5.0.tar.gz, while failing jobs were using the
wheel libvirt_python-7.5.0-cp36-cp36m-linux_x86_64.whl.
Install libvirt-python from source to avoid this issue.
Update the ansible-lint configuration to ignore errors coming from the
stackhpc.libvirt-vm role, fixing the tenks-tox-ansible-lint job.
