Adding New Health Check
Writing a new health-check follows the example outlined above.
Let's assume that you write a check called check_test. The first step is to create your new check file health_checks/checks/check_test.py.
Next, define your check command inside this file, add it to the gcm/health_checks/checks/__init__.py, and include it in the gcm/health_checks/cli/health_checks.py.
After that you can use the same boiler plate code as outlined before and add the core functionality of your check. Do not forget to test your check before submitting your PR.
Finally update the README.md file with information about the newly added check.
