Summary

First pass at adapting our devbox.json examples to use automatic the automatic dockerfile generation.

This adds install, build, and start to the examples.

How was it tested?

Reran examples + testing with docker build .

Adding the scripts to begin with. I'm not sure these are ideal for deploys the more I look at them though, the Stack examples are pretty heavy.
