/**
 * Adds or updates a layout asset resource (image, video,
 * etc.) and returns the URL reference to the resource.
 *
 * Note that layout resources are typically stored with:
 * - an "assets/" prefix (so we can find them)
 * - a name that starts with the cardId
 * - and a -{timestamp} suffix (to bust the cache)
 * Thus, 'update' is not really an update, it is:
 *    1. upload the new one
 *    2. find the old one (which has a different suffix)
 *    and delete it.
 *
 * This is why we cannot simply use upsertHubEntityResource
 *
 * @param type - type of the entity to upsert the resource for
 * @param id - id of the entity to upsert the resource for
 * @param owner - owner of the resource to add/update
 * @param resource - the resource to add/update
 * @param name - name of the new/existing resource file
 * @param extension - file extension of the resource (e.g. 'png', 'json', etc.)
 * @param context - contextual portal and auth information
 * @returns a URL reference to the newly added/updated resource
