We can export per protocol counters to Clickhouse but we do not export them via API:
```JSON_MODE=on sudo -E fcli show network_counters
{"success":true,"values":[{"network_name":"1.2.3.4/22","incoming_packets":69471,"outgoing_packets":31680,"incoming_bytes":82167074,"outgoing_bytes":6743429}]}```
We need to add this missing capability.
