Dockerfile generation

• Sets node:x.x.x as the base image, where x.x.x is the latest version (using https://semver.io), which satisifies:
• .nvmrc file
• OR engines.node property from package.json
• Adds source code into docker image
• Runs npm install
• Sets start command as npm start or node [entrypoint.js] depending on package.json settings
