This change is based on the CoreOS support for Oracle OCI bare metal machines, that was removed in 2018 with deba073. It's been adapted to modern systemd versions (using KeepConfiguration instead of CriticalConnection) and it works for any netroot, not just Oracle, as we never want to tear down the network if we're using a netroot, otherwise the root goes away when systemd does the switch-root operation.

Enable iSCSI netroot devices on Flatcar
This change enables the iSCSI module on dracut and changes the network behavior when Flatcar boots, to avoid bringing down the network when doing the switch-root operation.
This change is based on the CoreOS support for Oracle OCI bare metal machines, that was removed in 2018 with deba073.
Testing done
I've run CI with this change and it passed. I've also used the created image to mount a successfully mount an iSCSI netroot device and boot into the corresponding Flatcar instance.
