Change Name and IP svm Cloudstack 4.13

[Olivier Guin]

Hello, I just upgrade coudstack from 4.10 to 4.13. I had to destroy my 
System VMs and they recreated themselves with a new name and a new 
public ip address! How to change the name and ip? Ex s-191-VM or v-70-VM 
The name s-1-VM and v-1-VM is available ... Similarly, the IP address is 
xxx.xxx.xxx.187 whereas originally the IPs were at .1 and .2 It's 
cleaner :-) Regards, Olivier Guin
