VIP Legacy Related Posts (get post_id, title, url)
Don’t use for new projects, just use WPCOM_RelatedPosts directly, since it has hooks like jetpack_relatedposts_filter_args, jetpack_relatedposts_filter_filters
For backwards compatability, this function finds related posts on the current blog using Elasticsearch, then converts the results to match the original sphere results format.

| $additional_stopwords | array | No longer used. |
| $exclude_own_titles | bool | No longer used. |
Return Value
array: of related posts.
