Add authentication and brute force prevention to last weeks assignment.

• Clone this repo
• create .env based on .env.example
  • it's assumed that graphql server is in port 3000, auth server is in port 3001 and upload server is in port 3002
  • the auth server and upload server done in the labs should work. Only change the field name in multer to 'cat'.
• npm i to install dependencies
• npm run dev to start development server
• npm run test to run tests

• Your task is to complete all TODOs in the code until all tests are passed
• TODOs are located in resolvers and app.ts

• Interfaces are mostly the same as last week. The differnce is that now users have a role. This is because some operations need admin rights. The role should be embedded in the token.

• DB schemas are the same as last week

• Always empty your cats and users after tests.
