Investigate why `great_expectation.yml` gets changed

[linglp]

Sometimes great_expectation.yml gets changed, and when I tested uWSGI locally, I would get an error likes this: uwsgi PermissionError: [Errno 13] Permission denied: '/Users' It seemed like that great_expectation was trying to create a directory but got denied. I have not yet run into this issue on AWS, but a couple of times locally. Hopefully there's a way to "stop" great_expectation yml file from changing locally.
