FlipperBackgroundPlugin

Browse Source 
Summary:
Adds a new type of plugin: `FlipperBackgroundPlugin`
Background plugins are not torn down when the user switches to another plugin so they keep receiving messages in the background.

Background plugins need to use persistedState to keep their data. To handle the messages received in the background they need to implement a static method that merges a message with the current state from redux. The plugin doesn't need to call this method itself, it is called from `client.js`.

```static persistedStateReducer = (
    persistedState: PersistedState,
    data: Object,
  ): PersistedState
```

This method is used to handle messages in both foreground and background.
