Begin rewrite of Authentication Server

[Yorkshireman]

First one was good for a spike but needs rewriting in a cleaner more incremented style with clearly defined goals.

Tech Tasks

• Make sure master is up to date with develop branch
• Checkout to an early commit of develop
• Branch off develop with a rewrite (or similarly named) branch
• Setup a route with full integration test coverage that returns a simple JSON response body of:

{
  data: {
    message: "Hello World"
  }
}

• Commit that and merge it into the develop branch and deal with the inevitably massive merge conflicts
