Allow Custom Resource State mode to filter on resource labels

[blezoray]

Hi,

I'm using KMS v2.11.0 with --custom-resource-state-only=true mode.
In my custom-resource-state-config-file, I would like to filter some resources (StatefulSet, Deployment, DeploymentConfig) with specific labels.
Something equivalent to:

$ kubectl get statefulsets.apps -A -l 'accounting'
NAMESPACE                        NAME                               READY   AGE
dbms-db                          myq-orange-mariadb                 1/1     106d
dbms-ops                         generic-graf-orange-grafana        1/1     35d
dbms-ops                         generic-prom-prometheus            1/1     21h
...

I try to configure my custom-resource-state-config-file like this but it doesn't return any metric.

  # StatefulSet.apps
  - metricNamePrefix: mpms
    groupVersionKind:
      group: apps
      version: v1
      kind: StatefulSet
      labels:
        accounting:
    labelsFromPath:
      name: [metadata, name]
      namespace: [metadata, namespace]
      accounting: [metadata, labels, accounting]
    metrics:
      - name: managedresources
        help: MPMS Managed Resources
        each:
          type: Gauge
          gauge:
            path: [status, conditions]
            labelsFromPath:
              type: [type]
            valueFrom: [status]

Here are the logs:

Is it supported ?
