Kolla Build fails with ModuleNotFoundError for setuptools

[Till Plüer]

Hello,

we are trying to build docker images for kolla from source with ubuntu as the base distro.
During the build process (kolla-build ...) the openstack base container fails with ModuleNotFoundError: No module named 'setuptools' after downloading distlib.

Release: stable/ussuri
Kolla: 10.1.1
Type: source
Base Distro: ubuntu
Base Tag: 18.04

Ussuri builds fine both locally and on CI.
