[db] KG Database Selection - AWS Neptune

Problem to Solve

Given the sudden deprecation of Kuzu, the GKG team will be accelerating it's efforts to consider alternative graph databases that strongly overlap with Kuzu's querying capabilities and general performance, while also looking to ameliorate some of the downsides of Kuzu.

The intent of this issue is to provide a broad analysis of the features deemed necessary to the GKGaaS effort, an overview of how AWS Neptune performs, and some notes on deployment/resource provisioning for the DB.
