archive disconnected Android devices

Summary:
Adding a `archive` method to Android devices, that returns a new ArchivedDevice with the same properties as the Android device. This method is called when an android device disconnects and the new ArchivedDevice is added to the devices list. When the device reconnects again, the archived device is removed.

Currently only logs are persisted. In following diffs we can:
- add support for iOS
- move the persisted pluginStates to the archived device as well
