Virtual baremetal instances have their NICs show up as ens4
which doesn't play nicely as a default in devtest at
the moment.
Ideally we'd want it to be em1 like real baremetal
(which is why we put this in the baremetal element
to begin with). Turns out the baremetal element is
required in devtest so we can extract the ramdisk and kernel
so lets leave it alone for now and move this elsewhere
until we get a better solution for fake 'baremetal'
testing.

By default most cloud images have disabled the
udev rules which give us stable network interface names. While
this is a reasonable default for something like EC2 (the target
for these images) this is very bad behavour on bare metal
and can cause a "musical NICs" situation to occur where
on reboot the NIC names get swapped.
In this commit we re-enable stable interface naming by
removing the dev nulled rules softlink and installing
the biosdevname package. Once this is done interface
names should again show up as em1, em2 instead of
the old eth0, eth1.
We also remove some the common, statically configured
eth0 config files on some distributions. Equivalent
files (if needed) may be auto-generated by using
the dhcp-all-interfaces element.

Rather than using a script to mount the image using nbd to extract the
kernel and ramdisk, make a new element called baremetal, which contains
a cleanup.d script that will copy them out to <image name>.{vmlinuz,initrd}.
