bugfix: Graceful shutdown of VM
Cleanup phase of PVVP scenario sometimes causes server reboot. Following updates were made to prevent reboots: * sleep after VM OS shutdown allows QEMU to finish its own shutdown procedure * shared dir was mounted as read only to prevent its modification, which sometimes causes delays during shutdown; Also warning messages are causing CI jobs failures.
