Fix stability issues at the end of testcase run.
Cleanup procedure is performed at the end of each testcase run.
Procedure consists of termination of vswitch processes,
removal of unneeded kernel drivers, unmount of hugepages, etc.
There must be enough time for vswitch processes to terminate
properly before OS resources are freed. Otherwise OS stability
issues can be observed (e.g. server reboot).
Process termination is implemented by sending signal SIGTERM
to the process instead of previously used signal SIGINT.
