Summary: This is an initial step of rewriting the CLI interface to use `rnpm` one (commander, plugins etc.). It's scope is to move all existing commands to use rnpm CLI interface, so that we get plugins, flags and our existing ecosystem working out of the box. <s>This is still WIP and some of the commands are left commented out.</s> For the `config` of `rnpm` (functions get info about project and dependency), <s>I am thinking we can merge them with</s> we decided to merge it with [`default.config.js`](e57683e420/local-cli/default.config.js (L33)), so they are available on the `new Config()` [instance](e57683e420/local-cli/cliEntry.js (L59)) (which means we don't have to change anything and current plugins, like runIOS and runAndroid can just start using it [w/o depending on any extra argument](https://github.com/grabbou/react-native/blob/e57683e420210749a5a6b802b4e Closes https://github.com/facebook/react-native/pull/7899 Differential Revision: D3613193 Pulled By: bestander fbshipit-source-id: 09a072f3b21e5239dfcd8da88a205bd28dc5d037
