planned reboot of servers

[Evgheni Dereveanchin]

Hi everyone,

I will update and reboot more servers today, mainly:
artifactory.ovirt.org
ci-templates-repo.phx.ovirt.org
foreman.phx.ovirt.org
glance.phx.ovirt.org
graphite.phx.ovirt.org
proxy.phx.ovirt.org

As most of these are used by builds, I will temporarily
set Jenkins to maintenance mode. Builds will be added
to the queue and will run as soon as the maintenance is complete.

Regards,
