As of hypothesis/lms#2728 it is now possible to create a Hypothesis assignment that uses the book mentioned in the issue description (ISBN 9781400847402). In the process we discovered that recent changes on the VitalSource side appear to have broken the Hypothesis integration, so we need to chase that up with the VS developers.

Meanwhile on our side, the current VitalSource book selection UI hard-codes the book list and chapter data in the frontend. The next step is to move this to API views on the backend, which will initially return the same hard-coded data (see hypothesis/lms#2831) and then change the chapter-data API call to use the VitalSource products API instead of returning a fixed result.

There isn't an API yet that can return a list of VS books associated with the current course as far as I know, so we will have to look into options for that. One possibility for an initial release is that instead of a book list we present instructors with an input field where they can paste a link to a VitalSource book. From that we can extract the book ID.

The prototype requirements here have been satisfied. Please see #1100 (the original epic) and hypothesis/lms#2861 (the next epic we're working on here).
