Separated docker-compose.yml

Few comments on the proposition:

• a dedicated docker-compose.yml
• handle the auth inside of the application
• don't see no Web Server Gateway Interface, risk in production
• don't see workers set
• change the port to 5007 to avoid conflicts
• don't see any documentation, swagger or similar
• tried the test I don't get the output, are you checking connections by chance?
• A single file 500+ lines long, can that be split to help readability?
• don't get the offset logic, can you maybe explain it?
• you are putting a hard coded limit on buffer size but we saw messages being larger than 4MB
• hit /v1/topics and got 500: no errors (nor console or request response)
