### What happened? Currently, the Helm chart hardcodes all labels to `app: holmes` for both the Deployment and Pod template spec Request to add: - podLabels - custom labels applied to pod template spec - commonLabels - labels applied to all resources (deployment, service, etc.) I'm happy to contribute this if maintainers are open to it ### What did you expect to happen? expected to add pod labels ### How can we reproduce it (as minimally and precisely as possible)? no option to add podLabels in values.yaml (podAnnotations are available tho) ### Anything else we need to know? _No response_
