ODL oxygen provides a new framework to configure tunnels called autotunnels.
SFC requires tunnels to be flow-based and to arrange that in the autotunnel
framework, the OVS internal parameter of-tunnel must be set to true.
That parameter is not read in previous ODL versions. Therefore, this patch
does not break backwards compatibility.
