Public bug reported:
Removing router from l3 agent cause errors from neutron-metering-agent.
The neutron-meter-agent continues try to get traffic counters from
iptables on router-namespace, which is not exist after removing router
from l3-agent.
Steps to reproduce:
1. Create internal net, subnet, router. Set external gateway for router, add
interface to router for created net.
2. Create neutron-meter-label
3. Use 'neutron l3-agent-router-remove' command to remove a router from a L3
agent
