> Finally, does it also makes sense to add a `dns6_options` option? Or does this have no IPv6 counterpart in `nmcli` itself? Added dns6-options

> Thanks for your contribution! Can you please add a [changelog fragment](https://docs.ansible.com/ansible/devel/community/collection_development_process.html#creating-a-changelog-fragment)? Also extending the [unit tests](https://github.com/ansible-collections/community.general/blob/main/tests/unit/plugins/modules/net_tools/test_nmcli.py) would be helpful. Added changelog, not a big expert of unit test, and...

can't add test, but the change works fine. can somebody help me on the tests?
