Sync certain options updated via WPCLI instantly

[gititon]

This PR ensures that certain options updated via WP CLI sync instantly.

Testing instructions:
From a non-docker site (since it will only sync localhost as home option):

Try
wp option update siteurl https://my-new-domain3.com and
wp option update home https://my-new-domain3.com,
make sure both come through on your wpcom sandbox right away.

Change the domain values so they're eligible to sync and try again. They should sync right away.

This seems reasonable.

I was not able to test because I was not able to get this branch running on a non-local site.
The branch is not appearing as an option in the beta testing plugin.

If i were to test, i would do so by running your recommended command, and ensuring a sync happens immediately, and by trying a few other WP CLI commands and ensuring that a sync does not happen immediately.

didn't test, but looks sane
