Feature: Distinguish files depending on dev environment

[FlorentTorregrosa]

Hello,

I would like to avoid aving the following files packaged on production environment:

• .csslintrc
• .editorconfig
• .eslintignore
• .eslintrc.json
• .gitattributes
• sites/development.services.yml

I think a new config key like "dev" with the previous files has default values could resolved the problem.

And the files would be added/excluded depending if the require-dev packages are included.

If the maintainers are interested in this feature, thanks to tell me and I will try to make a pull request for that.

Sounds like a good idea to me.
