test(cardinal): add test for create, start, stop, purge (#32)

Closes: WORLD-362

## Overview

Adding unit test for create, start, stop, purge command

## Brief Changelog

- Added new test that cover create, start, stop, and purge command

## Testing and Verifying

Test will do this scenario
- run create command to clone starter-game-template
- start the cardinal
- hit `/health` endpoint and verify the response
- stop the cardinal
- hit `/health` endpoint and make sure it will be error
- purge the cardinal
