drivetrain elastic_properties missing in windIO 2 definition

[fzahle]

It appears that that windIO 1.x->2.x conversion of the 15 and 22 MW RWTs don't translate the section:

      elastic_properties_mb:
        system_mass: 821009.0477187126
        yaw_mass: 28740.99049474962
        system_inertia: [11242533.974662142, 14539734.272247598, 14648892.347010525, 799429.7807778214, 2997469.283520137, -290639.9124403294]

correctly, and it's now missing in the just merged v2, I missed that in the review. It seems like it is defined in the 2.x schema:

windIO/windIO/schemas/turbine/turbine_schema.yaml

Line 1051 in bcb64e6

elastic_properties:

but that section is not translated in the v1_to_v2 converter:

windIO/windIO/converters/windIO2windIO.py

Line 484 in bcb64e6
