Subject: bugfix: Graceful shutdown of VM - improvement
Cleanup phase of PVVP scenario sometimes causes server reboot.
Following updates were made to prevent reboots:
* better generic process termination procedure
* ovsdb is terminated after vswitchd termination
* vswitchd is terminated directly instead of parent sudo process
* already running VNFs are terminated in case of failure during
VNF start()
