Run SCAM6 Containerized Tutorial in LEAP-Pangeo Hub

[rabernat]

Some researchers have requested the ability to run the CESM CAM6 tutorial inside the LEAP-Pangeo jupyterhub. This would make it very easy for researchers to try out a "real" climate model.

The tutorial runs in a docker container. (Container installation instructions) This container contains its own self-contained jupyter and python environment.

Meanwhile, the LEAP-Pangeo environment itself runs in its own docker image. It is far from clear how we would merge these two environments. Here are some possible options.

• Try to tun the CAM tutorial into a conda-forge package - then we could just conda install it
• Try to make the CAM container launchable from jupyterhub - then we could easily start it up; however, we wouldn't be able to access the other pangeo packages. Maybe that is fine.
• Try to run docker within docker from the Pangeo environment - sounds complicated

Let's keep brainstorming and try to find some sort of solution.
