adding ability to stream output

[vsoch]

This also fixes a bug in the UI that we could not see output until the job finished. I also realized I had a natural inclination to want to click on the jobid after submit, so I've turned that into a bright pink link. Finally,
we add emojis/colors for the different result/state, and a new streaming logs endpoint (and example with the client)

Other updates:

• the container entrypoint can now take envars that will clone a specific branch and/or repo. This means we can more easily test on the fly.
• the functions to stream (or not) are provided separately in the client so it's more easy to discover

okay going to try something new - building the updated app server (for the python tests) from the code first, caching, and then loading into the next job.
