Python 3.8 on the Jupyter Hubs

Just a heads up that pangeo-docker-images recently updated its Python version from 3.6 to 3.8. This has been deployed to the hub at https://staging.us-central1-b.gcp.pangeo.io, and will be on https://staging.aws-uswest2.pangeo.io/ soon. We’ll roll it out to the production hubs later on.

You can try out your workloads on the staging hubs and report here if you notice any issues.
