Floating IPs momentarily removed from router on agent restart

[Carl Baldwin]

I noticed that floating IPs would be removed momentarily from the router on agent restart. This would cause a momentarily outage in network connectivity. This should be avoided.

I noticed this when testing with this change: https://review.openstack.org/#/c/30988/ which prevents routers from being destroyed and re-added.

I found that the floating ip was removed by a call to initialize the router's gateway interface.
