Service Model 10.1

The service model shall be updated to benefit from latest development :
_Controller customization (notably allows to define some notifications url in the scope of using a Kafka Broker, but also some parameters like OSNR margins or specific constraints for wavelength assignment)
_Operational mode catalog which translates OpenROADM optical specs into a Yang description of the specification (Noise mask polynomial fit used by the PCE, Transponders physical parameters (used by PCE + Renderer for explicit provisioning), Power mask (used by Renderer for explicit provisioning)
_Enhancement allowing to address the MDONS use case (asymetric service ending on different type of end points --> ODU handoff)
_Enrichment of service model to handle alien wavelength use case

Evaluation indicators:

_new yang models v10.1 published on master branch
_old models removed from master branch + adaptations to make the code work are merged
