Feature: Docker containerization

[rafi]

• Add initial Dockerfile with default environment options
• Add initial docker-compose configuration
• Add docker installation guide in README.md

Usage

• Either use docker-compose:

docker-compose up

• Or docker manually:

$ docker build -t gotty .
$ docker run --rm --publish 8080:8080 gotty

You can run one-off commands too, e.g.:

docker run --rm --publish 8080:8080 gotty --once top -o %CPU

FYI to anyone finding this, I've made a similar container in https://github.com/vorburger/cloudshell.
