 Right now, you can preload comments using embedding with the linked
 "replies" resource. This is great, but there's no way to know whether you
 should try loading more. Fetching the resource directly would give you the
 total in the `X-WP-Total` header, but you lose this when embedding.

 While this is generically a problem with the loss of headers from embedded
 resources, I don't think we really need a generic solution. Even when not
 embedding, a comment count is useful for archive display of a list of
 posts.

 We should add the comment count (using `wp_count_comments`) to the
 "replies" link:
 {{{
 {
     "replies": [
         {
             "href": ".../wp/v2/comments?post=42",
             "embeddable": true,
             "count": 12,
         }
     ]
 }
 }}}
