[horizon][kolla] xstatic libraries and setuptools 67.3.1

Hello, Recently setuptools 67.3.1 has been released, and it broke Kolla Horizon container builds. It seems that xstatic libraries rely on setuptools importing pkg_resources during build, which does not work in latest setuptools [1]. I raised a horizon bug #2007574 (https://bugs.launchpad.net/horizon/+bug/2007574) Raising awareness on the ML, because maybe that affects more projects than only Horizon. We’ve pinned to 67.2.0 in Kolla for now (in master and stable/zed, because earlier branches have a pin from u-c) [1]: https://github.com/pypa/setuptools/issues/3824 Michal Nasiadka
