Comment 1 for bug 1730477

It seems to me that the correct playbook to call would be https://github.com/openstack-infra/openstack-zuul-jobs/blob/master/playbooks/legacy/puppet-syntax-3/run.yaml

It has the comment "Autoconverted job legacy-puppet-syntax-3 from old job gate-{name}-puppet-syntax-3-ubuntu-xenial" in it, but it seems that this job was actually a centos based one, judging from the commands in the shell part.

The diff is very small between this playbook and https://github.com/openstack-infra/openstack-zuul-jobs/blob/master/playbooks/legacy/puppet-syntax-4-centos-7/run.yaml which is really a centos job.

I think we need to fix the called playbook in https://github.com/openstack-infra/openstack-zuul-jobs/blob/d46fb94e5699729bb8f8079fcd2a83abd85b31da/zuul.d/zuul-legacy-jobs.yaml#L4704 or rename the playbook.
