Public bug reported:

ENV:
platform: centos7.5
kernel: 3.10.0-862.11.6.el7.x86_64
neutron: master
openstack: devstack multi-node master

Problem:
The centralized fip will show up in the snat namespace if the host backing online.

Reproduce:
(1) create dvr + ha router, and connected to the private subnet and public network.
(2) associate 2 floating IPs (fip-1, fip-2) to two VMs hosting on the dvr_no_external host
(3) shutdown the `master` router hosting on physic host-2
(4) dis-associate one floating IP (fip-2) from the VM
(5) start the physic host
(6) let l3 agent processing and sync the routers

Then you can see the floating IP (fip-1) is show up in the started
host-2 snat-namespace.

Some outputs:
