Add Kubernetes labels as tags to docker metrics

[andrzej-k]

It would be good to tag docker metrics collected in Kubernetes environment with Kubernetes labels. Those labels are currently available as a separate metric /intel/docker/<docker_id>/spec/labels/<label_key>/value. This metric shouldn't be removed thou from the list of metrics collected by this plugin.

I want to have possibility to group metrics by pod namespaces or pod/container name. Currently I'm not able to show that on grafana with one query.

Those labels give me the possibility to group the metrics like @MichalMankowski asked? If yes, could you show me how?
