Add sample apps for IPv6 DNS configuration

Introduces six custom apps to configure DNS for an IPv6 network:
nc-create-xr-ip-domain-cfg-21-ydk.py - static (local) IPv6 hosts
nc-create-xr-ip-domain-cfg-23-ydk.py - single domain, various IPv6 servers
nc-create-xr-ip-domain-cfg-25-ydk.py - various domains, various IPv6 srvs
nc-create-xr-ip-domain-cfg-31-ydk.py - VRF-aware static (local) IPv6 hosts
nc-create-xr-ip-domain-cfg-33-ydk.py - VRF/ single dom, various IPv6 srvs
nc-create-xr-ip-domain-cfg-35-ydk.py - VRF/ various domains/IPv6 servers
