It is possible to configure a te-tunnel which has only a primary-reverse-path when it is a transit segment of a multi-domain end-to-end tunnel: in this case the explicit-route-object of the primary-path will be empty and the first and last explicit-route-object elements of the primary-reverse-path will contain the ingress and egress LTPs.

@italobusi @sergiobelotti : update the RPC model to support path computations also in these cases
The path computation RPC models assumes that:
It is worthwhile confirming these assumptions with te tunnel authors and to check how a te-tunnel with only one secondary path can be setup
