Add support for IPv6

[martijngonlag]

@paultyng First of all, thank you very much for all your work on maintaining this provider. I recently acquired some Ubiquiti hardware and figured I use this as an excuse to brush up my Terraform skills. So far I've gotten things working for the most part but I've run into a few issues, one of which is the inability to set up IPv6 with the unifi_network resource. I suspect it's because one of the parameters to specify the IPv6 DNS servers is not currently supported.

My Setup

1. UDM-Pro w/ 1 Switch and 2 APs w/ 1 Beacon
2. Deploying the following via Terraform (so far):
   • WAN (Connected to ATT Fiber)
   • LAN (Private, Guest, IoT, Media, Work)
   • WiFi (Private, Guest, IoT, Work)
   • DDNS (Cloudflare)

Description of Issue
The unifi_network resource has the parameter ipv6_interface_type. When this is set to pd and you run terraform apply the API will return a 400 Bad Request because of InvalidIpv6Addr

IPV6 RA is broken on att fiber's modem. it will tell you its giving your router a /56 but its actually giving you a /64 so you cant create subnets

Thanks for the response, though I am not entirely sure if this is related. Without Terraform I have IPv6 working on this deployment. It seem much more like one of the required parameters isn't covered?
