AP-Nimbus's datastore "REST" API endpoint to a database.
It's used to (very nearly 1) avoid direct client-direct <==> app-manager
communication. The idea being that it allows each component to scale independently of the others.
Documentation is available at https://ap-nimbus.readthedocs.io/.
[1] The only communication between client-direct and app-manager is when client-direct sends
an instruction to app-manager to run a simulation, and app-manager responds with an
identifier. Thereafter all communication is via data being sent to and retrieved from
the datastore using the identifier.
