Research python json entity mappers

[jghibiki]

Look for commonly used solutions for mapping json into objects, otherwise consider implementing one or use Schema, a dict, and utility functions directly.

The goal of this is to validate the schema of the pipelines as well as aid with setting up the initial state of the application. This state should be pushed into mongo after the first startup and on each subsequent startup we should check for differences between our schema and the mongo state. If there is a difference an update should be made to the mongo state. Ideally, there should be no state stored on the server threads when complete.

This is research only, implementation is #40
