Support collecting pod labels

[mtparet]

Is this a new feature, an improvement, or a change to existing functionality?

New Feature

Please provide a clear description of the problem this feature solves

We only can collect DGCM metrics containing pod name / container name / namespace name, it is not possible to collect any labels.

Feature Description

Hello,

We dig into dgcm exporter code base but there are no capability to collect pod labels and add these into metrics.

Do you have any plans supporting this ?

Best,

Describe your ideal solution

Just adding an option to collect the labels from the pods and perhaps also specify which label like in kube state metrics https://github.com/prometheus-community/helm-charts/blob/main/charts/kube-state-metrics/values.yaml#L342
