Description Gris Ge 2019-07-23 09:31:50 UTC 
Description of problem:

When applying empty state, the nmstate will move the DNS config to the default gateway interface instead of preserving old DNS config savings.

2. Create `empty.yml` with below content:

---
interfaces: []

3. sudo nmstatectl set empty.yml

Actual results:

The DNS config moved to the interface with default gateway.
