James Slagle 86608ee51a Don't assume single sub_node in nic config
This nic config only works when there is one sub_node since we were
cat'ing /etc/nodepool/sub_nodes_private expecting to get a single IP
back. Instead, cat /etc/nodepool/node_private which will be the IP
address of the given sub_node.
