#55592: Prime caches for featured images in post rest api controller

 Priority:  normal        |  Milestone:  Future Release
Component:  REST API      |    Version:  4.2
 Severity:  normal        |   Keywords:  has-patch
  Focuses:  rest-api      |
--------------------------+----------------------------
 In the post api controller, if the post type supports thumbnails, this
 results a query to be run for each post's thumbnail. For a REST API
 request with 100 posts in it, this can result in lots of queries. In core
 there is already a function called `update_post_thumbnail_cache`, used to
 prime post thumbnails. However, this does not seem to be fired here. A
 simple fix would be to fire `update_post_thumbnail_cache` in the post
 controller.
