How to pass extra labels to jupyterhub.labels ? Looks like it is not possible. In my use case i need to inject more labels at the top.
```
{{- /*
Returns an image-puller daemonset. Two daemonsets will be created like this.
- hook-image-puller: for pre helm upgrade image pulling (lives temporarily)
- continuous-image-puller: for newly added nodes image pulling
*/}}
{{- define "jupyterhub.imagePuller.daemonset" -}}
apiVersion: apps/v1
kind: DaemonSet
metadata:
{{- if .hook }}
name: {{ include "jupyterhub.hook-image-puller.fullname" . }}
{{- else }}
name: {{ include "jupyterhub.continuous-image-puller.fullname" . }}
{{- end }}
labels:
{{- include "jupyterhub.labels" . | nindent 4 }}
{{- if .hook }}
hub.jupyter.org/deletable: "true"
{{- end }}
{{- if .hook }}
