Continue working on cmds:

  - [x] when fail to build or launch cleanup dockers <none>? => point out the
        last built container so user could manually run it.
        => remedy with temporary make command
    - [x] Use regex for detecting container creation:
  - [x] Write out Dockerfile to `.test-flight` so users can see it
  - [x] Fix makefile using double dollar `$$` for awk commands
  - [x] consider non ansible cmd script mode => use ansible! Or use can just
        specify script via current dir as entire context already gets tar'd and
        sent up.
