[pve-devel] [PATCH container] PVE::LXC::Setup::Fedora: use systemd-networkd

[Stoiko Ivanov]

Upstream's templates seem to have switched to systemd-networkd for
fedora > 25. Since then various workarounds have been suggested (starting
the legacy network.service in /etc/rc.local). This patch tries to accomodate
both network-configuration options for the affected and available templates
(25, 26, 27), by configuring both services.
