      Given a system administrator using MCO to generate a YAML file at `/etc/nmstate` in an OpenShift environment to configure an IPv6 dual stack,
      When they restart the nmstatectl service,
      Then the original `.yml` file should remain in its location at `/etc/nmstate` and a symbolic link `.applied` pointing to the original `.yml` file should be created in the same directory

      Definition of done:

      • The implementation meets the acceptance criteria
      • Unit test and integration test are written and pass
      • The code is part of a build attached to a downstream errata

      What were you trying to do that didn't work?

      At  openshift hypershift kubevirt provider a yml config is generated at /etc/nmstate using machine-config-operator to configure ipv6 dual stack. This file is later on moved by nmstate to .applied and that breaks MCO InPlace upgrade since that's a configuration drift https://docs.openshift.com/container-platform/4.14/post_installation_configuration/machine-configuration-tasks.html#machine-config-drift-detection_post-install-machine-configuration-tasks.

      Please provide the package NVR for which bug is seen:

      How reproducible: Always

      Steps to reproduce

      1. Create config at /etc/nmstate
      2. Run systemctl restart nmstate

      Expected results

      The .yml file should still be there and a .applied symlink to it should be created to mark it.

      Actual results

      The .yml file is moved to .applied
