parallels: switch off offline management feature

which is on by default when a new VM/CT is created.
We should do this because this feature can't be controlled
by libvirt now and it sets up some iptables rules. So it's
better to do this to avoid potential conflict of different
set of rules or to avoid unexpected behavior.
