WIP towards Alma SRU model

[matt-bernhardt]

** Why are these changes being introduced:

For performance reasons, we stripped out holdings information from our initial Primo API call. However, we do want to display these holdings to users where they are available - so we need to add them back as an async API lookup.

** Relevant ticket(s):

• https://mitlibraries.atlassian.net/browse/use-598

** How does this address that need:

This adds an AlmaSru model that will handle these async lookups. This ticket calls for only the model, the rest of the integration will happen in subsequent tickets.

The model provides a lookup method which accepts an identifier argument. It validates that identifier, submits it to the Alma SRU endpoint, receives the result, and parses that response into a human-friendly format.

** Document any side effects to this change:

We consult a variety of external APIs in this application, and each of them follows slightly different patterns. Hopefully this does not exacerbate that range terribly.
