Containerize the applocation for better developer support

[rohansen856]

Summary

beacon-backend is a nodejs application that uses mongodb for databasing and redis for pub-sub architecture. Containerizing this application would greatly help the developers to setup and work with the repository. This will speed up the development and testing processes too.

• Cotainerizing the application using docker and docker compose
• setting up the database instances in docker compose file for easy database spin up
• modifying the .env.example and insert all the values as per the docker container

Implementation

• Create a Dockerfile for the NodeJS application
• Set up a docker-compose.yml file that includes:
  The application service
  MongoDB service with persistent volume
  Redis service
• Update the .env.example file with appropriate Docker network references
• Add documentation for local development with Docker
