Summary:
converted the network plugin to use DataSource / DataTable. Restructured the storage to contain a single flat normalised object that will be much more efficient for rendering / filtering (as columns currently don't support nested keys yet, and lazy columns are a lot less flexible)
lint errors and further `flipper` package usages will be cleaned up in the next diff to make sure this diff doesn't become too large.
The rest of the plugin is converted in the next diff
