Dualstack support for L3VPN - single router Dual stack

According to dualstack specification [0], this commit introduces changes
related to "one router solution" case.

* NeutronPortChangeListener: Create only one VPN interface instance
  for one neutron port. This instance can include a list of IPv4 and/or
  IPv6 subnetMaps, where addresses where allocated for spawned port.

* NeutronvpnManager: in createVpnInterface we no longer use routerId as
  argument, instead we will iterate over all port IP addresses to create
  according adjacencies objects and than, we pass composed adjacencies
  list to writeVpnInterfaceToDs method.
