How to configure labels in metadata of pod template for Dask Gateway Kubernetes workers non-invasively

[monarchofsage]

Is there any way to configure labels in metadata of pod template for Dask Gateway Kubernetes workers non-invasively?

For example, in spec->template->metadata->lablels:

apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx-deployment
labels:
app: nginx
spec:
replicas: 3
selector:
matchLabels:
app: nginx
template:
metadata:
labels:
app: nginx
spec:
containers:
- name: nginx
image: nginx:1.14.2
ports:
- containerPort: 80

I think it can be directly added to the "common_labels".

dask-gateway/dask-gateway-server/dask_gateway_server/backends/kubernetes/backend.py

Line 321 in 5771a3f

"app.kubernetes.io/version": VERSION.replace("+", "_"),

Is there any way to do that non-invasively through values.yaml?
