      As a system administrator, I need the nmstate kernel mode to support DNS and gateway configuration so that network settings can be applied quickly and efficiently during the early boot process.

      Acceptance criteria:

      Given a system adminstrator has Nmstate installed on a RHEL system booted without NetworkManager running and a YAML configuration file such as the one in the description is prepared with DNS and route settings, 
      When they execute the command `nmstatectl apply --kernel` along with the configuration file, 

      Then, the DNS resolver configuration is applied, the static routes are configured correctly and the interface is brought up with the specified IP address. 

       

      Definition of Done:

      • The implementation meets the acceptance criteria
      • Integration tests are written and pass 
      • The code is part of a downstream build attached to an errata
      • The changes are documented
