Title:
No network after subiquity LPAR installation on s390x with VLAN

Bug description:
I tried today an subiquity LPAR installation using the latest ISO (March 19)
that includes the latest 20.03 subiquity.
The installation itself completed fine, but after the post-install reboot the
system didn't had a network active - please note that the LPAR is connected to
a VLAN.

Wanting to have a look at the netplan config it turned out that there is no
yaml file:
$ ls -l /etc/netplan/
total 0
Adding one manually and applying it worked fine.
So looks like the installer does not properly generate or copy a
01-netcfg.yaml to /etc/netplan.
Please see below the entire steps as well as a compressed file with
the entire content of /var/log
