Fixed Issues (if relevant)

1. Magento 2.1.3 out of stock associated products to configurable are not full page cache cleaned #8009: Magento 2.1.3 out of stock associated products to configurable are not full page cache cleaned

Manual testing scenarios

preconditions: set indexers to scheduled and install sample data for configurable products

1. buy all available simples of a configurable product, so they become out of stock
2. run the indexer_update_all_views cron job
3. refresh the product detail page
4. the product should now be out of stock

Hi @ajpevers , thank you for your contribution. Changes from this PR look good and have been accepted, would you consider to backport them to 2.2-develop and 2.3-develop versions if needed? It also would be nice the PR and the commits have meaningful messages about changes performed in the pull request, so changes motivations are easier to understand in the future when seeking git history.

Hi @adrian-martinez-interactiv4, In 2.2-develop and 2.3-develop this is already taken care of. Thanks.
