Configuring RSVP-TE resource reservation confirmation

Reservation confirmation is initiated by the receiver, which sends the Resv message with an object
requesting reservation confirmation.
Receiving the ResvConf message does not mean resource reservation is established. It only indicates that
resources are reserved on the farthest upstream node where the Resv message arrived and the resources
can be preempted.
