Embed dask dashboard into the Jupyterhub

[roxyboy]

In the current pilot deployment, we configure the dask scheduler via dask.distributed and dask_gateway with the dask dashboard appearing as an external link:

from dask.distributed import Client
from dask_gateway import Gateway

gateway = Gateway()
cluster = gateway.new_cluster()

Would it be possible to have the dashboard embedded in the Jupyterhub by default as it would be for example by installing the dask-labextension package so that we could configure the dask scheduler directly via the dashboard?

This issue is not clear to me yet.

It is possible to use JupyterLab to present the dashboard in panels next to notebooks etc rather than in a separate tab. It is not very user friendly yet though. What you can do currently:

1. visit the dashboard in a separate tab and copy the full URL from your browser tab
2. go back to jupyterlab showing you the notebooks etc
3. open the dask-labextension panel on the left side
4. paste the URL in the text field on the top
5. press ENTER (don't press the search-like button, its not the same - see Enter Dashboard URL text field: pressing Enter is different from pressing the search button dask/dask-labextension#202)
