Reparent wheel-mirror jobs to new openstack-zuul-jobs versions
Reparent wheel-mirror jobs to new openstack-zuul-jobs versions

We moved the wheel build jobs into openstack-zuul-jobs so we could
test them speculatively.  These jobs already have a few fixes not
present in the project-config jobs.

Re-parent the build jobs in project-config (that are triggered by
periodic builds) to the openstack-zuul-jobs version.  A follow on
(https://review.opendev.org/731401) remove all these jobs, but the
requirements project must remove references on all branches first.
