DHCP configurability support for PXE
Similar to deploy_vlans, work with a DHCP configuration to work with PXE.
- Each testjob could need a dedicated DHCP configuration on the server, to allow for easy changes to tftp information in the DHCP responses
- May need VLANd support if needing to support broken devices without fixed MAC addresses
- Start up at test job start (after download) and tear down in finalize
Will need a DHCP server which allows safe changing of DHCP configuration on the fly, without needing root or restarting all the time.
