Cache product for mapFallbackUrl

[gibkigonzo]

What is the motivation for adding / enhancing this feature?

In 1.12 (develop) there is added new action for fetching category/product/cms_page by url_path - mapFallbackUrl. It makes request with one query that points to multiple entities. In this task we need to find a way how to cache product data in saveFallbackData. We need to handle all types of products (simple, configurable, bundle_options, custom_options, group). After reaching this goal, we will not have to make an extra request when product page is loaded.

What are the acceptance criteria

• - works for all type of products
• - after reaching product page we don't have additional request for product data

Can you complete this feature request by yourself?

• YES
• NO
