Finish Launch command and fix container bugs with it:

  - [x] Fix test-launch (to some degree)
  - [x] Bug, fix response code issue when running test-launch-f-s
    - [x] Fix template generation command to use mode dir
    - [x] Add `Logger.What()` command to help console debugging
    - [x] When error from create container, print it?
    - [x] Add `known_issues.md` to list known issues
    - [x] Copy inventory and playbook templates to `filemode` dir
    => Found that Dockerfile template did not specify `CMD` since I
       commented it out for testing. Remote Docker endpoint returned
       HTTP Status code 500 with no other information. Docker docs (atm)
       only say server error. Checked remote endpoint logs, and revealed
       that "no command was specified", which means no "CMD" was found
       in the Dockerfile. Think that docker error codes should come back
       with some messages.
