Hi,
there was a new version of 'importlib_metadata' library pushed to pypi.
Even though it's compatible only with py3, it's picked up by py2 pip.
I posted a patch to fix the version to the previous one:
https://gerrit.ovirt.org/#/c/112325/
If you see this failure in other suites than basic please notify me and
I will align the patch.
Regards, Marcin
