When using IPv6 link local address as DNS nameserver, interface name is
required, for example: `fe80::deef:1%eth1`
Example yaml:
```yml
---
dns-resolver:
config:
search:
- example.com
- example.org
server:
- fe80::deef:1%eth1
- 2001:4860:4860::8844
- 8.8.4.4
- 8.8.8.8
```
Restrictions:
* You cannot have 2+ interface names in DNS server names. Massive work
required to handle the DNS ordering between interfaces with the
design of NetworkManager.
* All other normal IPv6 nameserver will also stored in link local
interface if exists.
Unit test cases and integration test case included.
