EC2 migration

[RiyanMak]

Currently the auth is done with prod but we need to get it up and ready for deployment. It runs locally on an express.js server where we use in-memory session management. For deployment we need to migrate from this architecture to an EC2 instance where that will be used as the server to run the Node.js runtime and we need to use Redis to store the session information for the user if server were to crash. The focus currently is to migrate to the EC2 instance and get it ready for now and then slowly migrate to API Gateway + AWS Lambda + Redis.
