Class containing all the information uploaded when creating a new media item through the Google
Photos API.  Represents an intermediate step between a {@link PhotoModel}
and a {@link GoogleMediaItem} (which is created in response to a {@link NewMediaItemUpload}).
Note that this does not contain the content of the media item (photo or video)
itself, just the description and a {@code SimpleMediaItem} containing the upload token
corresponding to the previously-uploaded content.
