[tripleo] CI jobs broken due to #1966382

Hello,

The tripleo-ci jobs are broken due to the following bug. https://bugs.launchpad.net/tripleo/+bug/1966382 - Multiple tripleo jobs are failing because of "error: Multiple top-level packages discovered in a flat-layout"

The latest release of setuptools 61.0 caused it and more info is added here: https://github.com/pypa/setuptools/issues/3197

The team is working on fixing it https://review.opendev.org/q/topic:lp%252F1966382.

Till then please hold the rechecks and avoid workflowing patches.

Thanks,

Chandan Kumar
