We are not restarting VDSM within ovirt-host-deploy Ansible role, the VDSM
restart is performed in host-deploy part same as in previous versions.
Within ovirt-host-deploy-firewalld we only enable and restart firewalld
service.
comparing a successful add-host flow [1] to a failed one [2] we notice
that in the failed add host ansible logs in twice (session 10 and
session 11). Could it be somehow related? Notice that Session 11 uses
the OLD way (awk+grep based) to find vdsm's version.
