[WIP] Separate and simplify deployment

[azerella]

This PR is quite controversial as it refactors the project structure. Currently the web client is deployed using a very simple express server and is coupled to this for the search functionality, by introducing a microservice model we can decouple these two modules and have them as seperate deployments.

Pros:

• Enables isolated deployments of static files with a real web server like nginx or apache.
• Offers plug n' play functionality of the search api and web client, this workflow could make introducing the concept of a more popular CMS such as Gatsby.js easier.
• Isolated tests between search and static site modules
• Improved web security ( i.e Express.js was never really designed to be a production ready server, and writing servers in general is not a good solution ).
• Improved web performance ( i.e nginx offers gzip compression of static assets )

Cons:

• Potentially might make the project feel more complicated than it needs to be.
• A large refactor like this will take a considerable amount of time.

Ideas / Options:

• Integrate a static search library like http://elasticlunr.com/ or https://lunrjs.com/ which would void the need for this model, this would need to be throughly tested in older browsers and potentially hasn't been done before.

I am going to move this back into the backlog as we have some other priorities right now. I think there is a lot of potential here 👍
