advanced option: run outside container

[magland]

This is useful during development of an app, or troubleshooting.

On job submission window, click to reveal advanced options. Select "run outside container". On the compute resource, there needs to be some configuration that tells what main.py to run if that particular app is being run outside of the container. If that is not configured, it doesn't work.

Note that the spec.json will still need to be hosted on github. So not super easy to change the parameters.
