VIM-4074: VOD Model

[nicolelehrer]

Ticket

Required for Vimeans only VIM-4074

Ticket Summary

Add our model representation for VOD items (films or series) Augment our representation of video responses to handle videos associated with VOD items (trailer, film, extra content video, or an episode of a series)

Implementation Summary

VIMJSONResponseSerializer

• added to acceptableContentTypes so we can receive JSON data for ondemand endpoints

VIMVODItem

• these are the kind of objects received for a user's VOD library, films or series they have paid for

VIMVideo+VOD

• category on VIMVideo to house all VOD related helpers
• helpers to identify if a video is VOD when your origin is not the user's library, e.g. search results, feed

VIMConnection

• now supports ondemand and trailer connections
• videos connection gives us the the videos for a series
• new video count properties (e.g. extra, main, viewable counts) describe the number of videos associated with a VOD item

VIMInteraction

• buy, rent, subscribe interactions
• with corresponding properties like stream, expiration and purchase dates
• this tells us what kind of access someone has on a VOD item or one of its videos (if it was bought, rented or subscribed to)

VIMVideoPlayRepresentation

• corrected some naming inconsistency for VIMVideoPlayabilityStatus

Some to-do's

• API will update the date string format used for expires_time and purchase_time to match the format we already support. For now we use a helper method to parse this one-off format. See VIMInteraction implementation file for details.
• API will update purchase interactions so they exist on a film object. Purchase logic is in line with anticipated behavior but should be tested. See VIMVideo+VOD implementation file for details.

  How to Test

Code review only. See parent PR for more context
