Description Gris Ge 2023-05-11 07:50:54 UTC 
Description of problem:

Nmstate user might not know IPv6 has `autconf` property, so they might only have

```
ipv6:
  enabled: true
  dhcp: true
```

The state nmstate applied is not what customer desired as DHCPv6 does not have IPv6 routing information.


Hence nmstate should generate a warning message to user indicating nmstate is auto-fixing the desire state by enabling autoconf also.

Version-Release number of selected component (if applicable):
nmstate-2.2

How reproducible:
100%

Steps to Reproduce:
1. Use nmstate to apply this YAML:

```yml
---
interfaces:
  - name: eth1
    state: up
    ipv6:
      enabled: true
      dhcp: true
```
2.
3.

Actual results:

Only DHCPv6 enabled on this interface. Hence no IPv6 routing.

Expected results:

Both autoconf and DHCPv6 are enabled.
