    subnet create - segment aware auto-addr allocation
    
    When creating additional subnets with ipv6 auto-addressing
    ip allocation was added to existing ports without filtering
    on current allocation's segment.
    
    This adds fitering to only add auto-address allocation when
    the new subnet is on the same segment as the ports current
    ipam allocations.

  Since the port does not have 'binding_host_id' IP allocation on the
  routed provider network was deffered on create. However when adding
  another ipv6 stateless subnet, implicit address allocation is added to
  the port. This allocation should have been deferred.
