[WIP] Expose a search profile for popular pages
The apps teams are putting out a feature to show popular pages
nearby the user. These new profiles weight very heavily towards
page popularity in the content namespace, and the incoming links
on all other namespaces. Not expecting much usage outside the
content namespace though.
Bug: T157843
