Comment 2 for bug 1468865

Afaik the issue is that quite a few things have changed in the last 2 months on the stackforge gerrit and now we are lacking some of the code for the now enabled jenkins jobs.

Specifically we need to:
- enable puppet 4: https://review.openstack.org/#/c/179645/
- fix a lint typo: https://review.openstack.org/#/c/195760/2
- fix dependencies for concat and apache: https://review.openstack.org/#/c/193869/ or https://review.openstack.org/#/c/179645/1
- add acceptance tests for beaker: https://review.openstack.org/#/c/195905/ and as a consequence of the new centos7 test we now need to support centos7 (this one is the real issue, as currently EPEL and ceph packaging are incompatible): https://review.openstack.org/#/c/156458/

So apart from the centos7 support I think we would have all of the issues covered, now we just need to put them together to pass the gate.
