Implementation of TN NSSMF WF on SO

(1) Workflow of Allocate TN NSSI
(2) Workflow of Deallocate TN NSSI
(3) Workflow of Activate and Deactivate TN NSSI
(4) Workflow of Modify TN NSSI

NOTE:
   1. The full implementation of TN NSSMF consists of two layers:
      (1) The TN Sice definition layer, which is an orchestration
      layer that provides the NBI of TN NSSMF to its consumers
      (i.e., it concerns the "what" question), and (2) the TN slice
      realization layer, which is responsible for the actual network
      configurations of TN slicing (i.e., the "how" question). The first
      layer is done on the SO (i.e., this changeset), while the 2nd
      layer is implemented on the SDNC. That's why this changeset is
      relatively simple, since the "real work" is done by the SDNC.
   2. This changeset depends on the common NSSMF WF
      (https://gerrit.onap.org/r/c/so/+/111477)
