LP#1688099: Popularity parameter for the number of OUs that own a title

Creates a new badge that calculates a score based on a count of libraries
that own a copy of a title. The badge is based on libraries that are the copy's
circulation library. The intent of the badge is to measure the breadth of
ownership within a particular consortium with the hope that it doesn't
generate as many 'false hits' that are seen with the similar Total Copy Counts
badge.
