OpenStack or Bust, Part 4: node interfaces

# NB: in case you're wondering, pn=public_net and sn=storage_net. The trailing "i" indicates infrastructure as opposed to development, quality_assurance, continuous_integration, research, etc. The pn/sn code simply indicates where the box's default gw is. As I intend to segregate the mgmt and storage traffic, sn will soon become a misnomer. Oh well.
