[TRNSPRTPCE-513] Update GNPy REST implementation

Relates — Wed, 15 Jun 2022 14:36:29 +0000

Current GNPy Docker is based on an old version of GNPy code. Update the code to the latest version available. This version might be the one available on Telecominfraproject/oopt-gnpy at experimental/2021-candi (github.com)
Ultimately we shall try to use PyPy in place of Docker.
An analysis shall be made to identify :
_Whether hybrid mode is required or not (Could base the calculation on worst case, especially if we do not have the ability to provide easiy to GNPY spectrum allocation with existing channels)
_If we have libraries corresponding to the latest specifications of OpenROADM (B100G) or if we need to build them)
_If we can make our own evaluation of the OSNR and the penalties and add just add the contribution associated with non linear effects (extracting from GNPy results just the contribution associated with non linear effects

Functional tests shall be updated to include some tests with 200/300 and 400G.
