Issue description

NW chapter (11) of RH124v9.3 setup has a default setup of following which prevents update of /etc/resolv.conf when a connection is brought UP:

[student@workstation ~]$ cat /etc/NetworkManager/conf.d/99-cloud-init.conf 

1. Created by cloud-init on instance boot automatically, do not edit.
   #
   [main]
   dns = none

Steps to reproduce:

1. nmcli con up any_connection_profile_with_DNS_config

Workaround:

/etc/NetworkManager/conf.d/99-cloud-init.conf  file can be removed and NetworkManager service can be restarted to show normal behaviour.

Expected result:

"nmcli con up" should update /etc/resolv.conf (or material should be updated accordingly)
