Title:
  PortInUse exception leaves orphaned ports

Status in OpenStack Neutron (virtual network service):
  Expired

Bug description:
  While bringing up 1000 VMs with Heat, some VMs are in error state.
  After deleting the VMs, not all ports are removed.
  The next time VMs are created, they fail due to no IP addresses left.

  
  Note, initially there are 7 ports, no VMs
  804 VMs are created, 811 ports

  After deleting the VMs, 248 ports remain
