Feature Request: Rule Sets

I find that some rules are rules I want while developing day-to-day, and some I would prefer to run periodically. A good example is arrow-body-style when building out React components - Temporarily adding some logging before rendering means changing between implicit and explicit return and the addition of curly braces. I would prefer to allow both day-to-day, however this is something I would want to run before a release. It might be nice to allow rules to be gathered into named sets that can easily be toggled on or off. One set could contain ongoing rules and one rules that are run occasionally. Obviously I can do this on an individual basis, but doing to as a set would make more sense.

There are some approaches.

1. Prepare several .eslintrc files. For example: eslint src and eslint src --config .eslintrc-release.json
2. Use .eslintrc.js and tweak configuration by environment variables such as process.env.NODE_ENV.

I agree that multiple configurations is the best way to go. To minimize duplication in your configuration, you can have one primary configuration file and then have others that extend that file and only do minor tweaks, so that most of the configuration is in the primary file.
