Comment (by johnjamesjacoby):

 [https://core.trac.wordpress.org/attachment/ticket/25344/25344.2.diff
 25344.2.diff] does the following:

 * Registers the global `site_meta` cache group
 * Introduces `*_network_meta()` functions
 * Replace `$wpdb` queries with calls to the above functions
 * Remove network level `alloptions` and `nooptions` cache implementation
 💜

 A few things to note:

 * Transients still call the old `_network_options()` functions to keep
 filters intact
 * Transients still use the same old cache group
 * The `site-options` cache group is in use by a bunch of things that
 aren't actually options, so it remains untouched and unaltered for this
 patch
 * Unit tests pass for me, but failed the first time I ran them. I'm not
 sure why, because the `restapi` test group is causing out-of-memory issues
 on my MacBook out-of-nowhere, and I can't complete the entire suite. (I
 can run this on my Pro later and figure it out.)
