Granular Flags/Vars for Datastore Connections

[corkrean]

Problem Statement

Sometimes, people don't store their DB connection info as a connection string, and they choose another method (e.g., a k8s secret with separate fields for the endpoint, password, username, etc.) It can be cumbersome for these people to format this connection data as a connection string.

Solution Brainstorm

Separate flags/vars for each component of a connection string.
