Ouroborus hello world, ruby + docker

[jeffque]

Actually, docker isn't properly installing the gems requested to just run a docker run ouroborus:latest

But work in "debug mode".

Also, created a simple Makefile to create image and run the container with proper configuration:

• make image: creates image
• make run: execute container, depends on image
• make debug: execute with sh as entrypoint mounting the volume as ./
• make debug-no-mount: like make debug, but no mounting
