Title:
  NSX: remove_router_interface might fail because of NAT rule mismatch

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

Bug description:
  The remove_router_interface for the VMware NSX plugin expects a precise number of SNAT rules for a subnet.
  If the actual number of NAT rules differs from the expected one, an exception is raised.

  The reasons for this might be:
  - earlier failure in remove_router_interface
  - NSX API client tampering with NSX objects
  - etc.

  In any case, the remove_router_interface operation should succeed
  removing every match for the NAT rule to delete from the NSX logical
  router.
