Title: speed up node cleanup for big clusters

When working with cluster sizes > 200 nodes, the known_hosts and /etc/hosts cleanup is extremely slow. I'm currently working with a cluster of 400 nodes, and removing a single node takes almost 45mns when starcluster is run from a m1.large instance.

With this change, the remove node takes 4mns on my 400 node cluster, with the same end results.
