Stopping and starting VNFs and VDUs

Stopping VNFs/VDUs allows maintaining them and installing software updates.

When a VNF/VDU is not in use, it can be stopped to free up computing resources and use them for other purposes. You can also stop a VNF/VDU that is causing errors and faults to isolate the problematic component and resolve the issue while maintaining functionality.
