Update the host_id for network:router_gateway interfaces
The ports owned by a router_gateway need to get its host_id property
updated during the failover of a router. Otherwise the port connected
to the external network will always have its host_id set to the value
obtained during creation.

Title:
Port information (binding:host_id) not updated for
network:router_gateway after qRouter failover
Status in neutron:
Fix Released
Bug description:
[Impact]
When using l3 ha and a router agent fails over, the interface holding
the network:router_gateway interface does not get its property
binding:host_id updated to reflect where the keepalived moved the
router.
[Steps to reproduce]
0) Deploy a cloud with l3ha enabled
- If familiar with juju, it's possible to use this bundle
http://paste.ubuntu.com/24707730/ , but the deployment tool is not relevant
1) Once it's deployed, configure it and create a router see
https://docs.openstack.org/mitaka/networking-guide/deploy-lb-ha-vrrp.html )
- This is the script used during the troubleshooting

#!/bin/bash -x
source novarc # admin
neutron net-create ext-net --router:external True
--provider:physical_network physnet1 --provider:network_type flat
neutron subnet-create ext-net 10.5.0.0/16 --name ext-subnet
--allocation-pool start=10.5.254.100,end=10.5.254.199 --disable-dhcp

export TENANT_ID_DEMO=$(keystone tenant-list | grep demo | awk -F'|'
'{print $2}' | tr -d ' ' 2>/dev/null )
neutron net-create demo-net --tenant-id ${TENANT_ID_DEMO}
--provider:network_type vxlan

# verification
neutron net-list
neutron l3-agent-list-hosting-router demo-router
neutron router-port-list demo-router
----- 8< -------
2) Kill the associated master keepalived process for the router
ps aux | grep keepalived | grep $ROUTER_ID
kill $PID
3) Wait until "neutron l3-agent-list-hosting-router demo-router" shows the
other host as active
4) Check the binding:host_id property for the interfaces of the router
for ID in `neutron port-list --device-id $ROUTER_ID | tail -n +4 | head
-n -1| awk -F' ' '{print $2}' `; do neutron port-show $ID ; done
Expected results:
The interface where the device_owner is network:router_gateway has its
property binding:host_id set to where the keepalived process is master
Actual result:
The binding:host_id is never updated, it stays set with the value
obtainer during the creation of the port.
