Build a CLI interface for react-scripts

[ocavue]

Is your proposal related to a problem?

Currently, react-scripts is just a simple "script", with almost zero arguments/flags.

$ yarn run react-scripts 
Unknown script "undefined".

$ yarn run react-scripts --help
Unknown script "--help".

This can cause

1. Make users confusing without --help
2. Difficult to add more features. For example, I want to build my project with a NODE_ENV value different than "production". With a CLI interface, I can use something like vue-cli-service build --env test to present this feature.

A complete CLI interface can solve these issues.

Describe the solution you'd like

Maybe we can choose a famous npm package to implement it.

commander for example, who has already been installed by react-scripts: react-scripts > html-webpack-plugin > html-minifier > commander

And of course, there are many other options in the JS world.
