MAAS to ignore boot request from specific mac addresses

[Blake Rouse]

I just tested this with MAAS. I added a device with the MAC address of one
of machines that normally PXE boots from MAAS. I then powered it on, it PXE
booted from MAAS then loaded the pxelinux.0 and MAAS told it to boot from
its local disk.

Adding the ability to change this behavior would be a good improvement.
Possible options could be:

* Ignore
* Boot local
* Poweroff

I filed a bug about this here:
