[pve-devel] [PATCH stable-4 container] use systemd-networkd for ubuntu >= 17.10

[Thomas Lamprecht]

From: Dominik Csapak <d.csapak at proxmox.com>

Ubuntu Artful uses systemd-networkd now,
but we have to delete the default netplan config from the
upstream lxc container, and enable systemd-networkd
