Decoupling

First, let's update the server so that it can interactively pause and resume the game.

1. Run the PrintServerHelp function in internal/gamelogic as the server starts up so that you can see the commands the user of the REPL can use.
2. Start an infinite loop.
3. At the beginning of the loop, use the GetInput function in internal/gamelogic to wait for a slice of input "words" from the user. If the slice is empty, continue to the next iteration of the loop.
4. Check the first word:
   1. If it's "pause", log to the console that you're sending a pause message, and publish the pause message as you were doing before.
   2. If it's "resume", log to the console that you're sending a resume message, and publish the resume message as you were doing before. The only difference is that the IsPaused field should be set to false.
   3. If it's "quit", log to the console that you're exiting, and break out of the loop.
   4. If it's anything else, log to the console that you don't understand the command.
5. Test the app:
   1. Start 3 clients, each in their own terminal. Use the usernames washington, napoleon, and churchill.
   2. Run the server again to pause the game.
   3. You should see 3 queues created in the RabbitMQ management UI, each with its own copy of the "pause" message.

Run and submit the CLI tests.
