    Stop returning code 500 when serving stale data.
    
    Until now, when the hourly updater has not run for 6 hours or more,
    the server responds to all queries with a 500 Internal Server Error.
    This seemed to be a good idea, because users would tell us when the
    hourly updater was broken and we could fix it.  But actually, these 6
    hours were chosen arbitrarily, and each application should decide for
    itself when it considers data as stale.  That's why we're taking out
    the check and stopping to return a 500 status code because of
    potentially stale data.
    
    Implements #16907.
