HONEYCOMB-118: extend classifer model to support node names.

* configuration write is supported (updates local cache
  with relative node mapping)
* operational read is supported only for nodes with existing
  relative node mapping
* ACL support (using vpp-classfier or ietf-acl model)
  is not affected by the patch (tables/sessions for access controll
  refer to neighbour nodes as packet-handling-action, not vpp-node-name)
