Jarrod Johnson 5dfbeef79c Advance state of cloning
Have imgutil complete the capture process, splitting work
between target and repository.

Provide hook through kcmdline to induce installtodisk.

Have installimage reboot system cleanly when done.

Have new /etc/confluent in cloned system.

Hook for post scripts to execute.
