Refactor Docker Work Flow to Permit Automatic/Manual Refreshes and API Proxying

[3lpsy]

This PR drastically overhauls the current docker implementation to support multiple use cases.

Use Cases:

• Serve the built/compiled frontend via nginx and proxy requests to the backend api (written in go) through the same endpoint/port
• Serve the built/compiled frontend via nginx without proxying to the backend api
• Serve the loaded (not-synced) frontend via npm start
• Serve the frontend mounted with source code on the host system. This allows for mounting the source as a volume and restarting the app automatically via npm start or manually (via refresh) with nginx

Detailed instructions are included in the README.md file.

Dependencies Added

• cra-build-watch

External Breaking Changes:

• API Endpoints must sit at /api/v1/{endpoint} in order to proxied effectively

Other Considerations

• When websockets are introduced, the dynamically generated nginx config file in docker-run.sh may need to be altered slightly.
• A few files were automatically formatted via tslint so there may be some whitenoise. This can be fixed later.
