Method to retrieve carousel contents

[Jeff Davis]

EG 3.7+

There doesn't seem to be an API call to retrieve the list of bib records for a given carousel. This would be handy for sites that want to use Evergreen carousel data externally without screen-scraping, iframes, widgets, etc. (compare bug 1882982), as well as for future carousel-related development within EG.

Working branch user/jeffdavis/lp1951318-retrieve-carousel-items has a work-in-progress implementation of such a method:

https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/jeffdavis/lp1951318-retrieve-carousel-items

No pullrequest yet since this needs testing to ensure it returns data usefully and doesn't break existing carousel display. I won't have more time to devote to this in the immediate future, so if someone else feels like looking at it in the meantime, please feel free. :)

This seems to work without breaking anything, so I've added a pullrequest.

A worthy refactoring which I like an approve of. Merged to master for 3.9. Thanks, Jeff!
