This adds two new Noble nodepool builders to our inventory. When we
deploy these two servers we will shutdown services on nb01 and nb02 and
put those older servers in the emergency file to force the new Noble
nodes to build images. This should give us a safe way to rollforward
onto the new platform and catch any problems.
