[dask] Make vanilla-pad work properlly with dask
In this MR, I'm.
- Wrapping the pipeline with DaskWrapper, because it wasn't. I think that's why things were not working for you with SGE @ydayer.
vanilla-padwas creating SGE jobs AND running everything locally.
- Added the options "--dask-partition-size" and "--dask-n-workers", so the user has some freedom to set these parameters if the heuristics in place are unpleasant.
I'll merge this one right away because of the workshop.
Feel free to open issues if any
