Boundary layer results can be saved in vtk format. Correctly handle inputs fuselage for fuselage and added fuselage type in c++ classes

Now the viscous solver is created after the interface. This allows less user inputs and avoids conflict between parameters. The blSolverInterface class was reworked and documentation was improved. The sections can now have no wake or only one side (for fuselage for example). Bug fix here and there and ajusted tests. Only the onera validation case is up to date.

Now a python virtual env is created to use the latest versions of scipy and numpy

Small modifs on validation cases and add them to the validation job on the pipeline

docker with updated VTK version & scipy 1.10

Back to blaster docker image and remove MKL
