[FYI] Jenkins maintenance today 18:30 TLV

Hi, http://jenkins.ovirt.org will be restarted for plugin updates today at 18:30 TLV time, expected downtime is 30 minutes. Patches sent 30 minutes before might not get checked, patches sent during the downtime will get checked when Jenkins is back. If patches you sent did not trigger CI, you can login after the downtime and re-trigger them manually. Thanks, Nadav.
