- create the cluster-utils.sh in pkg/kube for a number of functions
- get EdgeNodeClusterStatus from 'zedkube' for cluster status, cluster nodeip, cluster prefix, etc
- a background process to monitor the cluster mode changes
- implement cluster mode change logic and operations for change from single-node to cluster, or from cluster back to single-node
- save kube /var/lib at single-node first time setup for later use when the mode changes back from cluster mode to single node
- display eve-release string for get node OS-IMAGE field
- this patch tested still works in kubevirt single-node case.
- some of the external_boot_img changes in the patch is from Andrew's diff.
