Move settings, launcherSettings, GKs to app / flipper-server-core

Summary:
This diff moves a lot of stuff from the client to the server. This diff is fairly large, as a lot of concept closely relate, although some things have split off to the earlier diffs in the stack, or are still to follow (like making intern requests).

This diff primarily moves reading and storing settings and GKs from client to server (both flipper and launcher settings). This means that settings are no longer persisted by Redux (which only exists on client). Most other changes are fallout from that. For now settings are just one big object, although we might need to separate settings that are only make sense in an Electron context. For example launcher settings.
