- Refactored `test/e2e/framework` so that the core framework is smaller. Optional functionality like resource monitoring, log size monitoring, metrics gathering and debug information dumping must be imported by specific e2e test suites. Init packages are provided which can be imported to re-enable the functionality that traditionally was in the core framework. If you have code that no longer compiles because of this PR, you can use the script [from a commit message](https://github.com/ku...

    * `main:app`이 파이썬의 `import` 문법과 흡사한 면이 있다는 걸 알 수 있습니다:

        ```Python
        from main import app
        ```

    * 곧, `main:app`안에 있는 콜론의 의미는 파이썬에서 `from main import app`에서의 `import`와 같습니다.
* `--workers`: 사용할 워커 프로세스의 개수이며 숫자만큼의 유비콘 워커를 실행합니다. 이 예제에서는 4개의 워커를 실행합니다.
* `--worker-class`: 워커 프로세스에서 사용하기 위한 구니콘과 호환되는 워커클래스.
    * 이런식으로 구니콘이 import하여 사용할 수 있는 클래스를 전달해줍니다:
