netman is a simple tool which applies ifup command to network interfaces which are down.
Used in the virtual machine which is integrated to Network Analysis Platform.
There is a service file called netman.service. It needs to be placed
under /lib/systemd/system/ in the virtual machine. (Ubuntu 18.04)
The service file indicates that netman will run once when system booted then exits. (No further run). In order to run service file, released version of netman should be deployed into the virtual machine from releases page
