[PONv6] Add 3 new fields to NC.

[ecigar13]

Reason for Change:
This change allows DNC to publish MACAddress, PrimaryIPV6 and GatewayV6 to NNC. CNS uses these fields to program routes in Swiftv2 Vnetblock scenario (single tenant)

CNS queries NIC MACAddress against the IDMS API to ensure Swift NIC is programmed.
