nbn domain

[matt-beanland]

add an nbn domain where 'create a new domain nbn with a resource nbn_ethernet comprising of dedicated uni and avc resource. The uni will be related to an ntd resource. The circuit and the uni will be related, and the uni will be aggregated by a cvc resource which will terminate at an nni_group resource, which itself comprises of mulitple nni resources.'

did this with Claude in Visual Studio, results were pretty good. Had to steer Claude a little bit more.

• CVC is Connectivity Virtual Circuit, not commerical virtual circuit
• The CVC resource aggregates AVC's, not UNI's. Each AVC will have a related UNI.
• the avc's cvlan_id should be assigned from the cvc

Have checked in the initial vibe. Will need to work on it a bit more to get a composite nbnEthernet resource built correctly. We want to be just like nbn here, in that the RSP will specify the CVC. Unlike NBN we'll have CVC's as a resource, so we can simply relate using assigner.

Have got basic NBN domain modelled, and working on refactored diffo.
