Prepare the current knowledge graph for the new ontology

[mike-audi]

We have a knowledge graph with a ton of company data already. Investigate if we can easily migrate all of that data over. If not, drop the entire DB.

Acceptance Criteria:

• A hosted knowledge graph ready to accept new vertices and edges

[mike-audi]

We're going move to an entirely new DB and let it rebuild.

It's not worth rebuilding each key for each company.
