This is the commit message #2:

ci: Pin setuptools to a range that still ships

Recent setuptools releases (82.0.0 and later) have removed the
``pkg_resources`` module. Our docs environment still depends on
``pkg_resources`` transitively via ``openstackdocstheme/pbr``,
causing import error when run under newer environments.

Modeled off of CID's ironic commit.

NOTE(elod.illes): ironic-python-agent-builder's zed branch moved to EOL
so it has to be used from zed-eol tag for the jobs. Furthermore,
sushy-tools is cycle independent project. in Zed release 0.21.0 version
was officially used.
metalsmith jobs used centos8 which is not available anymore in zuul,
hence this patch removes them from the gate.
Additionally, ipa-tempest-bios-ipmi-direct-src job and
ipa-tempest-uefi-redfish-vmedia-src job are intermittently failing,
which makes the gate unstable and the error seems to be environment
related. Setting them as non-voting to do not waste CI resource.
