[stable-only] Fix gate and remove zuul config error

This is a combination of 2 commits.

1. [Stable-Only] Pin setuptools for tox docs

This was somehow missing from the cherry-pick of the original fix [0].

Furthermore, swift-dsvm-functional started to fail on this branch, so
to quickly unblock the gate, it is set as non-voting, until it will be
fixed.

(cherry picked from commit 52370443b3)

2. Drop openstack-*-node-bionic nodeset definitions

In order to be able to edit these on the master branch, we need to drop
them on the stable branches first.
