When A DVR floating IP associate to a port, the `floatingip_update_callback` will immediately start a `start_route_advertisements` to notify DR agent that FIP bgp route.
But this bgp route is not right, its next_hop is set to snat gateway IP address.
And then after `periodic_interval` seconds, then the DR agent will resync that DVR fip route with new next_hop to the correct FIP namespace fip-device IP address.
Reproduce:
1. create a DVR router 1, set gateway
2. create a network/subnet, and connected to the DVR router 1
3. create a VM 1
4. bind a floating IP to that VM 1
5. in DR agent LOG, you may see the following infos:
