Notify router_update after directly gateway IP change
If directly change router gateway port IP address, the gateway IP
does not changed in router related namespace in l3 agent side. This
patch adds a method to catch a 'PORT' IP change event, and notify
the L3 agent.

Title:
[l3] router agent side gateway IP not changed if directly change IP
address
Status in neutron:
Fix Released
Bug description:
ENV:
stable/queens
Problem:
if directly change router gateway port IP address, in l3 agent side, the gateway IP does not changed in router related namespace.
Testing is on the stable/queens, but master code is basicly same.
Reproduce:
(1) add new IP (172.16.200.30) for the gateway port:
openstack port set --fixed-ip ip-address=172.16.200.30 df7c2bd7-3fa4-4ff3-9b09-a2f30f04d974
(2) remove the old gateway IP (172.16.100.30) from port:
openstack port unset --fixed-ip subnet=fda73661-1bcf-4916-b488-1d76dab7de36,ip-address=172.16.100.30 df7c2bd7-3fa4-4ff3-9b09-a2f30f04d974
