Update zuul jobs

Remove publishing jobs, this project is not under governance and cannot
publish to docs.openstack.org. Replace the publishing jobs by jobs that
just test but do not publish.

Import missing jobs and templates from central project-config so that
all jobs are here. This allows also to remove the non-voting
requirements-check job from the gate (note that gate jobs should never
be non-voting).
