ORBIT-USER: -k option

[Haris Kremo]

My question is with respect to -k option with nodehandler4:

Looks like node handler 4 reboots the nodes every time it is invoked.
With previous version the nodes were not turned off after an
experiment, as well as not rebooted.

Is the change made intentionally or it is a bug? I see incentive to
reboot nodes: to start each experiment with clean state. But then -k
includes time waste related to boot just as running node handler
without that option.
