Network interface creation active or not user case

[Ya Lian Pan]

Need to identify whether the following user case is reasonable:
1. guest is active

2. user adds a network interface inactively, which will punch a network.doscript to VM reader

3. user adds a network interface actively, which will punch a network.doscript to VM reader, and zvmguestconfigure service is called to handle the network.doscript file

If it is a reasonable user case, both network.doscript files will take effect, and the first one will restart the whole network, will cause the all network service(such as ssh) to be stopped.

[Huang Rui (bjhuangr)]

In my opinion, it's a valid case. Change zvmguestconfigure to deal with such case.

Not a common case, fix when convenient.
