What happened?

In #1052 support was added for 'custom' workload types, which is great because we now don't need our own custom relabels. However the new custom workload types use the original casing of the owner_kind whereas all other workload types are lowercase. We also built our own recording rules with lowercase as per the upstream method, this is now causing us duplicate records (one PascalCase and one lowercase) which break the kubernetes-mixin dashboards that use workload type.

Please provide any helpful snippets.

apiVersion: monitoring.coreos.com/v1
kind: PrometheusRule  
spec:
  groups:
    - name: k8s.rules.custom
      rules:
      - record: namespace_workload_pod:kube_pod_owner:relabel
        expr: max by (cluster, namespace, workload, pod) (label_replace(kube_pod_owner{job="kube-state-metrics", owner_kind="StrimziPodSet"},"workload", "$1", "owner_name", "(.*)"))
        labels:
            workload_type: strimzipodset
