Public bug reported:

In case when DVR router is used and there is vm with floating IP created
on compute node, it will create fip-<network_id> namespace and will also
create additional port (and public IP address) with device_owner like
"network:floatingip_agent_gateway"

When vm is deleted from compute node, qrouter- namespace is removed but
fip- namespace is still there.

I'm not sure if that is something what is done like that "by design" and
should be like that or maybe it should be changed and such namespace
(and network:floatingip_agent_gateway port) from such host should be
deleted in such case to safe some public IP addresses.
