NOTES

• Because Ubuntu 18.04 has cloud-init , the script will not change the resolv.conf file but modify the cloud-init config to change dns servers.
• Be careful for variable names. This script uses "server" for CentOS , "dns" for Ubuntu and Windows.

Known Issues

• When giving a single dns to "Windows" server , win_dns module crashes. You should give 2 dns servers at the same time.
