- Disabled auto-provisioning of IP settings on private network (eth1),
  beause it failed to resume/reload properly after the initial install.
  The provision.sh script is now taking care of the initial static IP
  assignment.
- Added compute1 and compute2 VM's with their own provisioning script.
  These machines get enough packages installed, so they can be
  provisioned and managed via fab commands from the main contrail node
- Set contrail VM as the default VM and disable auto-start for compute1
  and compute2 in order to just work with contrail for standard, single
  node setups.
