 caching.2.diff 40228.improved-caching.2.diff]

 Addes some improves to the `get_site_by` function.

 - If the lookup is by id, don't use `get_sites`, just use `get_site` and
 do the network_id compare  using the `WP_Site` object for better
 performance.
 - Implement the `blog-lookup` cache in `get_site_by` to save lookup on
 domain + path, as this cache key is invalidated in `clean_blog_cache` and
 `get_sites` is invalidated a lot in high traffic sites.
