Changes for quantum networking and single NIC

Move network resources onto quantum's network bridge.

Create baremetal nodes with only one NIC, instead of two.

Disable quantum's DHCP server so that baremetal dnsmasq works,
  but inject a static IP which matches the IP assigned by quantum.
Add virtual power manager.

Add a commented-out section to localrc, to make it easy to enable
virtual power manager.

Update notes.md to reflect this change.
