New: Configuring core options in Config Files

[mysticatea]

Rendered RFC

Summary

This RFC adds several properties into config files to configure core options. People can use config files (including shareable configs!) instead of CLI options in order to configure some linter behavior.

Thanks for working on this RFC! I left a few thoughts.

@not-an-aardvark Thank you for your feedback. I updated this RFC. I think it has addressed your concerns.

the rendered link seems broken.

Oh, thank you. I have fixed the link.

I have updated this RFC for some feedback.

• Move coreOptions.* properties to top-level.
• Disallow ignorePatterns in overrides entries to avoid confusion with excludedFiles property.

No concerns from me at this point.

@kaicataldo @not-an-aardvark Does the latest update solve your concerns? If so, I will move this RFC to the final commenting.

Just one question about renaming property names, but otherwise this LGTM. Thanks for working on this!
