The FlowMetrics API needs to be improved to allow having labels and/or filters set on list fields (NetworkEvents is a list).

For instance, we want to be able to define a metric such as:

Def:{
  Name: network_policy_verdict
  Filters: [{Key: "networkEvents.type", Value: "acl"}]
  Labels: [SrcPod, DstPod, networkEvents.name]
  Remap: {"networkEvents.name": "name"}
}

(this is just an example, not a design reference)

Here's a working example of a metric using this feature, with the Interfaces field:

apiVersion: flows.netobserv.io/v1alpha1
kind: FlowMetric
metadata:
  name: per-interface
  namespace: netobserv
spec:
  metricName: per_interface
  type: Counter
  labels: [Interfaces]
  flatten: [Interfaces]
  remap:
    Interfaces: interface
