[prometheus] Persistance lables are not being added to PVC

[rasmusson]

Describe the bug a clear and concise description of what the bug is.

I was trying to addlables to the PVC the helm chart is creating for prometheus. example values
server:
persistentVolume:
labels:
test: enabled

these are not being added to the PVC being created. Other setting work, for example setting annotations
Looking at the template it look like the lables are simply not included. Only server lables
labels:
{{- include "prometheus.server.labels". | nindent 4 }}

Compared to annotations

annotations:
{{ toYaml .Values.server.persistentVolume.annotations | indent 4 }}
