Implementation of VNF using WLS as message transport

Add check to vnf_nr_handle_param_response for when phy_info is not found

The WLS VNF is in charge of Enqueueing the used blocks after usage for transport, this is done by keeping track of all blocks used, and calling WLS_Enqueue for all of them upon receiving a SLOT.indication
