Phoenix flipper - client plugin

Summary:
Created by running scarf flipper-plugin command as suggested in [doc](https://www.internalfb.com/intern/staticdocs/flipper/docs/extending/desktop-plugin-structure/).

Will be modifying test & index later to receive other data

- also created [GK](https://www.internalfb.com/intern/gatekeeper/projects/flipper_phoenixinternal/)

Question
- Is there a way to hide the plugin until feature is complete, besides GK?
