Public bug reported:
If we trying to create meter-label-rule and there is a router without
external gateway, then the metering agent will raise an error:

Steps to reproduce:
1. Create internal net, subnet, router. Add interface to router for created
net. Boot vm in created net.
2. Create neutron-meter-label
3. Try to create meter-label-rule
4. Rule not appear in iptables on router-namespace and after that we can see
traces in neutron-meter-agent's logs like above.
