Features of the sessionless config-sync surface — launcher/mobileconfig
with mobileconfigsessionless, which the app sends from a separate config
client: no API-analytics group (priority, x-fb-friendly-name,
x-fb-request-analytics-tags) and no x-fb-appnetsession-nid/-sid pair.
One set for every sender of that request, so the surface's wire shape is
declared once.
