Create REST interfaces for calling the underlying system

[mikaturunen]

Technical

Start off from: https://github.com/OpenSecTre/sword/blob/master/server/server.js

• Express.js: http://expressjs.com/, http://expressjs.com/en/starter/basic-routing.html

Essentially we are creating a REST interface for Express.js that can be called from /api/test for example. Call to the interface should make a simple system call and return the result in a JSON format to the frontend.

I can also help with this as needed. I'll create the docker environment and can hop on this to see how it flies.
