Revert "Remove duplicated job from openstack-ansible"

The non-voting version of the job is still required for newton
whereas the voting version of the job is used for ocata onwards.

This reverts commit 4168ea16ee2c578d68ab7e1696a3c9bd83fe6219.

Comments have been added to each job in the check queue to
explain where they're used for easier maintenance later.
