Using snakeviz on a jupyterhub installation

[bsimpson53]

Hi,

I recently stumbled across snakeviz, and I found it really helpful and noticed the notebook magics, it seems to be really suitable for jupyter and works with a local jupyter install but not on jupyterhub.

I'm intending to use it on a jupyterhub installation and I think I can get it to work using:

• https://github.com/jupyterhub/jupyter-server-proxy (to handle authenticated requests through the cluster)
• https://github.com/yuvipanda/jupyter-launcher-shortcuts (to add a shortcut to start a server)

...and provide some extra options to snakeviz:

• --url_basepath=< url basepath to server for the proxying >
• --fs_basepath=< filesystem basepath to write files to and whitelist Alternate root directory #62 >

I have noticed that there's a problem with the server in that it allows you to export any file on the file-system #62

The other approach (possibly better but more time consuming) would be to write a jupterlab extension and jupyter server extension, but then they would need to be maintained.

I'm happy to contribute back these changes (they might be a bit "rough and ready") but before I do this, has anybody tried to get it to work jupyterhub already and have a better approach (perhaps I've missed a simpler solution)?

Saw there's a rejected pull request relating to #62 => #136

@bsimpson53 Did you end up giving this a try?

@rcthomas got side tracked, other things took priority, I still think it's worthwhile though and it's on my list
