Pulp: enable metric relabeling
What
Enable metricRelabelings and clean up relabelings so we can just set it using helmfile later.
Why
We're currently not seeing the type label on the metrics for the nginx ingress controller pod, although they're set on the pod level.
I reckon it has something to do with the relabel config: https://prometheus.io/docs/prometheus/latest/configuration/configuration/#relabel_config
