How do you separate credentials from the _settings.yml file so that you don't store them in version control?

Is there a way to import an external file for credentials (in my case, elasticsearch preferably with the API key)? We would like to have our fscrawler _settings.yml file in version control, but do not want that to contain credentials. So far the only way I can tell to do this with the documentation is to hack around using --username and then use redirects to send the information on the commandline from another file.

I agree. I opened an issue to track it. I don't know yet how to do this though.
