Running outside of docker deletes all containers and images with no warning.

At a minimum, there should be something in the README.md warning about this behavior. Even better would be requiring some command line flag to auto-clean which defaults to false.

In a related note, I'm wondering how the tool can work under docker without deleting all the containers and images, but if it is run outside of docker, then this is necessary.

@matthias50 Because it will still perform the pull manifest operation, but it will skip pulling the blobs, so you still get monitoring but "less".

Feel free to prep a PR against the README with the warnings, as it sounds like a good idea
