3rd party CI should not be affected by recent changes. As there interface to our
CI system is gerrit (review.openstack.org). Zuulv25 is really only meant to be
consumed by openstack-infra as a stepping stone to zuulv3. At this time I would
not recommend people update their CI systems to consume it.

This was and still is controlled by nodepool[1]. Even when we used jenkins,
nodepool was responsible for creating our jenkins slaves. Under zuulv25, this is
still the case except they are called zuul workers now.
