[Paraview] ParaViewWeb/Visualizer file upload server

[Sebastien Jourdain]

Hi Louise,

The upload part can be managed by the launcher or the actual ParaViewWeb
server (the later require additional args at startup).
That part was meant to be a proof of concept so we could create a form and
let the user upload the dataset that he wanted to visualize with Visualizer
either before or while Visualizer was running.

If you are using Apache, that means you will also have to forward /upload
to the launcher like you did with /paraview.

On the other hand creating your own endpoint for uploading file, should not
be too difficult either.

Here is the relevant part of the code that will register /upload if the
configuration provide such thing:
