Replace transportpce-topology yang by existing OpenROADM models

The yang model 'transportpce-topology' (in ordmodels/network/src/main/yang/...) was originally created in order to add missing elements from OpenROADM topology models such as the associated-logicial-connection-point or the otn-link-type (OTU4, ODU4, ...).

However latest versions of OpenROADM network models now implemented in TransportPCE are handling these elements. In addition, having a specific TransportPCE model in the same location as the OpenROADM official ones is problematic for the future project's migration preparation towards Chlorine.

Modify code to replace the use of this specific yang model by OpenROADM models where possible.
For other elements (especially otn-linke-type) that don't have replicas in OpenROADM models, move the enum to the existing 'transportpce-networkutils' yang model (in api/src/ hand/yang/...).

Acceptance criteria : the code does not bring regression
