Create mini datalake database

[DJensen94]

Create models and handler to create mini datalake to store org and scan data

🗣 Description

This PR creates the models and code to generate the Mini Data Lake database, that will store data from the various teams and will eventually serve the Crossfeed application database data.

💭 Motivation and context

In order to expand Crossfeed's capabilities the database needs to be expanded to hold different vulnerability and scan types and hold data specific to each source, this new schema will allow us to house data from any source as it is expanded upon.

The schema will likely have some adjustments as time goes on and new sources are added.
