Changelog:
----------

[General] [added] - Add `templates` to `react-native` package.

We need a `template` to initialize new RN project from `react-native-cli`. We are planning to remove `templates` from `cli` to be always synced with chosen rn version. Issue for that in `react-native-cli` is here: https://github.com/react-native-community/react-native-cli/issues/39 .
