Dockerize Graphql Rust

More current version at https://github.com/jayy-lmao/rust-cult-graphql-server

This project is currently for demonstrating the use of dataloaders in a rust-based graphql server. This demo uses:

• actix-web a high-performance webserver for rust https://www.techempower.com/benchmarks/
• juniper a popular rust graphql framework https://github.com/graphql-rust/juniper
• A dockerfile which creates a from scratch minimal sized container
• Cults (more to be added)

There are definitely some improvements to be made in db requests, pagination etc. Let me know if you spot anything you think is top-priority!

Running locally

simple as docker-compose up, crazy! Then navigate to http://localhost:8000/graphql

  name: String!
  members: [Person!]!
}

type Mutation {
