[neutron] neutron-metering-agent track router and floating IP traffic


it looks like every notification is bound to the label:

grep -A6 bandwidth meters.yaml
   - name: 'bandwidth'
     event_type: 'l3.meter'
     type: 'delta'
     unit: 'B'
     volume: $.payload.bytes
     project_id: $.payload.tenant_id
     resource_id: $.payload.label_id

Wouldn't it make sense to change this to:

   - name: 'bandwidth'
     event_type: 'l3.meter'
     type: 'delta'
     unit: 'B'
     volume: $.payload.bytes
     project_id: $.payload.tenant_id
     resource_id: $.payload.label_id + "_" + $.payload.tenant_id
