Decouple route information updates from code base deployments

[KyleDolezal]

Overview
Route information can be updated on an automated basis without redeploying the application.

Problem
Updating route information requires the deployment of the entire codebase. This is a manual task, and the codebase (including presentation layer and business logic) need not be tied to the json data for routes.

Solution

• Fetch route data from a remote host instead of the local codebase. A proof of concept is here. By replacing the route json, the information data can be updated without a deployment.
• Consider automating the process of calculating/curating route information. GitHub Actions can be set up to run on a cronjob basis in order to automate this process.
