I believe these tasks were originally added when we switched the Sepia
lab from static IP assignments to DHCP. We can get rid of these tasks
now because:
1) All our testnodes are using DHCP now and have been for at least a
year
2) NICs are already configured in our FOG images and OVH nodes get
configured via cloud-init
