Subject: [PATCH] deploy, scripts: provide list of images and script to pull
 and push all Longhorn component images to user provided registry

This help to remove the extra dependency on different container image
registry. Docker Hub now holds all Longhorn components' images.
Also, users can easily pull all the necessary images to their
air-gap environment

Longhorn #1419
