travis: migrate travis plans to run in a Docker container

Add Dockerfile to create build environment for mraa
Add docker-compose.yaml file to easily execute build tasks
Add .dockerignore file
Modify .travis.yaml file to use docker and docker-compose for building
Modify package.json.cmake to run a simple load test for node.js
