Title:
  allow ports to be created on networks that do not exist in nvp

Status in OpenStack Quantum (virtual network service):
  Fix Released

Bug description:
  If a network exists in the quantum database but not in NVP we should
  allow someone to create a port on this network though set the status
  to error. The reason for allowing this is if one deletes a network
  from NVP and the dhcp agent goes to create it's dhcp port on this
  network currently an error will be raised to the agent and it will
  enter a constant cycle of resyncing.
