This reverts commit cfb36f1b81d706badb95fab06ddbdd95f4f59d67. NetworkManager uses it's own built in dhcp client now as does systemd, basically dhcp-client is irrelevant for most use cases now so it shouldn't be there by default. Instead, we are removing the "dhcp-client" from the kickstart file so it is not needed to build the images. Signed-off-by: Jan Kaluza <jkaluza@redhat.com>
