Request all metadata for Images plugin before export

Summary:
Fresco plugin on the desktop side used to ask for all the image list along with the metadata when it was mounted. The mobile side never sent the image list and other information if not requested from it. That means, although Fresco plugin is a background plugin, there weren't any messages sent from the mobile side. Thus there was no trace available for Images plugin when the trace was exported. This diff, adds a hook which gets called before the export, where we request all the metadata from the mobile SDK.
