This config was sending all logs to localhost:42185 in UDP but nothing
was listening on this port (it was supposed to be fluentd to aggregate
logs in Wendelin).

This was actually creating a weird scenario where qemu was temporarily
listening on UDP on localhost:42185 and receive the packet from
rsyslogd (which was transmitted to the guest machine and considered a
martian packet there)

Otherwise if playbook stops after removing ifupdown
then the ORS becomes unreachable because ors-image-backports
playbook might not get executed properly to configure
systemd-networkd

Patch for callboxes and simboxes

Otherwise playbook will fail upon first installation
because we save logs to /opt/upgrader in ors playbook,
and launch upgrader playbook later

See merge request nexedi/slapos.package!182

  Packages already exists on OBS.

ors57 failed to run playbook when installing pip because
this package was missing
