Add an internal ESLint rule prefer-negative-boolean-attribute

[fisker]

Use positive [...=true] may cause problems, when ecmaVersion is not correct. #1146, fisker/eslint-plugin-prettier-doc@f1b1c6f

Maybe I can try to make a proposal in eslint-plugin-eslint-plugin later.

Does eslint not offer a way to load a plugin from a file instead of a module?

[fisker]

This being a loooong story, and the reason is ridiculous, add a plugin path in config, ESLint can't get a plugin name to use...

eslint/eslint#3458

Unless you use the ESLint API, you can't add plugin in other way.

You could hack the module resolution like node core does but i guess it's even worse of a hack 😉.
