* vagrant: workaround to fix private network ip address in fedora

Fedora stop supporting syconfig network script so we added a workaround
here
https://github.com/hashicorp/vagrant/issues/12762#issuecomment-1535957837


to fix it.

* netowrkmanager: do not configure dns if using systemd-resolved

We should not configure dns if we point to systemd-resolved.
Systemd-resolved is using NetworkManager to infer the upstream DNS
server so if we set NetworkManager to 127.0.0.53 it will prevent
systemd-resolved to get the correct network DNS server.

Thus if we are in this case we just don't set this setting.

* gitlab-ci: mark fedora packet jobs as allow failure
