Documentation: How to access Dashboard when using dask-kubernetes in a Jupyterhub environment

Hi!

We are currently setting up Dask enabled Jupyterhub over Kubernetes, and want to use dask-kubernetes as it is better maintained than dask-gateway and fits our use case.

The problem we are facing is how to give the user access to the Dashboard from the Jupyter lab, as Scheduler/Dashboard are running in a separated pod from the Jupyter server one.

After some searching, I essentially found https://kubernetes.dask.org/en/stable/installing.html#dashboard-access, which is linked to Kubeflow, but I believe can be re-used in some way for Jupyterhub environments. Digging in issues here didn't help me better, found some ingress of kube forward discussion, but I'm not sure about those.

Are there some best practices in order to implement this need? We would be happy to help contributing some documentation about the good solution here!
