fc23 jenkins slaves

Hi all, I merged [1](and a 'hotfix' [2]) which basically allows to run our puppet code on fc23 and cleans up some packages we had. This caused a restart of postgresql on all slaves, so far I did not catch any jobs failing due to that. the second implication is that we have zero slaves in 'error state'[3]**, so we have a 'fresh ground' and can monitor from now on if new puppet errors pop up. Thanks, Nadav. [1] https://gerrit.ovirt.org/#/c/57847/ [2] https://gerrit.ovirt.org/#/c/58229/ [3] https://foreman.ovirt.org/dashboard ** to the time of writing :)
