Clark Boylan 23826e05a6 Only alias docker registries on test nodes
Skopeo has problems with ipv6 address literals just like docker as they
use the same underlying checks for url validity. However, we think we
can fix that by using a port forward from the executor to the buildset
registry so that skopeo can connect via ipv4

Go back to aliases the registries on test nodes via /etc/hosts.

Pull artifacts from the intermediate registry
This role will pull any artifacts built for changes ahead of this
change which have been placed in an intermediate registry into the
buildset registry for this buildset.
Run this in a trusted pre-playbook at the start of a job (which, in
the case of multiple dependent jobs in a buildset, should be at the
root of the job dependency graph).
This requires the :zuul:role:`run-buildset-registry` role already
applied. It also requires an externally managed "intermediate"
registry operating for the use of Zuul, and it requires "skopeo" and
"socat" to be installed on the Zuul executors.
