The daily images have exactly the same setup as the 16.04.3 images you pointed to. snapd is not included in the base livefs, but is in /pool/ as a deb that gets installed over top if the 'server' task is selected when installing. If it's intentionally unselected, then it's not installed.
Furthermore, this has nothing to do with cloud-images, so marking that task Invalid as well.
