Current metrics are using a filter for deduplication, such as: "FlowDirection: 0"

Which makes the flows having the new Inner state being excluded from the metrics, which they shouldn't.

This results in under-evaluated traffic rates in metrics

Reproduction steps:

• Deploy default netobserv w/ sampling=1
• Deploy some workload providing consistent network load, for instance mesh-arena:
  • kubectl create namespace mesh-arena ; kubectl apply -f https://raw.githubusercontent.com/jotak/demo-mesh-arena/main/quickstart-naked.yml -n mesh-arena
• Let it run ~5 minutes
• Check netobserv plugin, Overview tab, filter on Src ns=mesh-arena => you should get a byte rate ~31 KBps
• Check Observe > Metrics, enter promql:

• • sum(rate(netobserv_workload_ingress_bytes_total{SrcK8S_Namespace="mesh-arena"}[1m]))

Expected results:

Same as in overview tab, ~31KBps

Actual results:

It's less than expected, around 23 kBps (in fact, that will depend on how pods are allocated to nodes)
