Rewrote script (build-img) that generates a QCOW2 (virtual machine)
image with StarlingX pre-installed. This will allow users to create
virtual machines more easily using a disk where verything is already
installed.
This script updates a standard iso file with a default menu choice
(e.g., AIO/serial console) and adds a kickstart script that configures
the network; then boots the ISO in QEMU and lets it install to a disk
image.
The generated image only works in QEMU because it has a few things that
are specific to that emulation:
* /etc/lvm/lvm.conf restricts LVM to only the bus/port/device type that
QEMU emulates SATA as
* It includes configuration for the network device named "ens3", which
is QEMU's default
