Re-add config

[jason-fox]

@apozohue10 - You are right to exclude config.js in the .gitignore but you need a config.js in the build to run the app. This is now just a POJO style object with defaults like the template. Some users may choose to inject config.js as a docker volume rather than configure via ENV as well.

This also fixes the Unit-Test fail

Once you have merged this, could you move the release tags (or delete and re-create them) so I can complete the FIWARE release? Thanks

Hi Jason,

I have been looking for another solution. I am going to add this sentence to the travis file:

cp config.js.template config.js.

And also I added these two ones for the Dockerfile:

RUN cp config.js.template config.js
RUN rm config.js.template

I have tested and the Travis tests run correctly and the Docker Image is working too. Do you think it make sense?

[jason-fox]

Leaving the config.js in the codebase(.gitignore protected) and not copying the config.js.template over makes more sense to me, in that if run locally and I make changes to my own config.js I see those changes, so it is confusing if I make my own docker images for my own changes to be overwritten with the template.

Leave config.js.template as a template I say and keep travis and the docker file simple.

Easiest way would be to:

docker checkout master
docker reset --hard 0ce701d
docker push -f

and then merge this.
