Vue: document api

[felixgabler]

We can already begin documenting parts of our API.
Many endpoints around tools and jobs are already mostly finished (if they change in the future, we will just update them).
I propose a layout along these lines:
https://learning.getpostman.com/docs/postman/api_documentation/intro_to_api_documentation/

If we share the postman collection we can also use it for development purposes which would be great.

@conrizzo please take a look at https://github.com/proteinevolution/Toolkit/wiki/API-Definition-(WIP)
The way to approach this ticket would be to go over all services when running the toolkit. For each route, try to get it to fire in the browser while inspecting the network through the DevTools. Then you can easily document the query, parameters and response object structure.
