[Container-tools] hacking on atomicapp-run

Vasek, Langdon and I hit a few issues trying out atomicapp-run[1]
- needed empty dict in answers.conf: "general: {}" (maybe it just doesn't handle null value?)
- provider was kubernetes even when answerfile was "docker" and default[2] was hacked with hard-coded "docker". Output[3]
- I got further with a custom kubernetes application but it failed on install[4]. I was able to install when entering the container[5] but hit this run error[6]
