Change default nic to e1000 for bionic PXE testing

Browse Source 
Network booting on bionic, by default, doesn't work
with the virtio "firmware" which lacks the PXE stack.

iPXE has traditionally been in the e1000 driver and it
shouldn't be too much overhead for test VMs.

The default libvirt network interface card type has been changed from
``virtio`` to ``e1000`` in order to support testing on Bionic. Users should
not experience any issues as a result of this, however the
``bifrost-create-vm-nodes`` setting ``test_vm_nic`` can be used to explicitly
choose ``virtio`` network interface cards.
