Refactor config

[olafveerman]

Refactor config so it's easier to deploy the frontend with CF. Fix #181 and #183

This makes significant changes to the Docker image. The built site will not be pre-baked in the image, instead it is to be built when the container starts. This allows environment variables to be passed like below.

@danielfdsilva This works well, but is slow. Launching the container takes a couple of minutes.

Also, when you build the image, make sure you have do it from a clean project without node_modules or dist.

version: '3'

services:
  ram-frontend:
    image: ram-frontend-test
    command: sh .build_scripts/serve.sh
    environment:
      API: 'https://happy.api.io'
    ports:
      - 8080:80

When this receives your thumbsup, I need to change this in the docker-compose config on the backend as well.

@olafveerman Couple of improvements:

• Add node_modules and dist to .dockerignore so there's no need to delete the folders when building.
• Instead of having the command in the docker-compose.yml this could be the default command for the image making it easier to run even in standalone format. You'd use docker run ram-frontend instead of docker run -it ram-frontend sh /source/.build_scripts/serve.sh. For this simply add CMD ["sh", "/source/.build_scripts/serve.sh"] to `Dockerfile
• Update readme with instructions on building and running the docker.
• Add a message at the end of serve.sh stating that the app is now being served. I was left waiting for nginx to print out something

Overall it works great! 👍
