Title:
  Manually created port by admin can be assigned as a second gateway to
  an existing router

Status in neutron:
  Expired

Bug description:
  ____________
  Description:
  As an admin one can manually create a port on a network and assign it to a router (which already have a gateway) as a gateway by adding "Device Owner" = "network:router_gateway" and "Device ID" = "<router ID>"  
   
  basically I see two issues here:
  1. When Manually creating a port on an external network it cannot be deleted via API access (Horizon or CLI command)
  2. The manually created port can be assign as a "Device Owner" = network:router_gateway to a router that already have a default gateway which cause one router to have two default gateways.

  ________________
  Version-Release:
  openstack 6.0.3-0
  openstack-neutron-2014.2.2-3
  horizon-2014.2.2-2
  ____________
  Environment:
  All-in-One
  RHEL 7.1

  ___________________
  Steps to Reproduce:
  1. Create Neutron external network and a subnet
  2. Create a router and set a gateway the external network
  3. Add a port and assign it to the router you created with "Device Owner" = "network:router_gateway" and "Device ID" = "<router ID>"
  4. Try to delete the manually created port
  _______________
  Actual results:
  Port cannot be deleted with the following: Error: Failed to delete port: Port 0ff48364-dcb1-44a4-b064-b1df5e9cb911 has owner network:router_gateway and therefore cannot be deleted directly via the port API.

  _________________
  Expected results:
  Port can be deleted
  Cannot assign two gateways to one router.
