[Tracking] Transfer data to OSN -> Virtualize OSN dataset with beam -> View dataset __repr__ in catalog

[norlandrhagen]

Meta tracking task to see if we can:

1. Move a set of archival files off of NCAR or another cluster into LEAP's OSN bucket.
2. Create a virtualizarr reference from the files on OSN.
3. Add the virtual dataset reference to the LEAP catalog with a repr that includes: engine = 'kerchunk'. Can we configure the 'engine' argument in the displayed xarray/python repr? #150

@norlandrhagen this is the dataset I mentioned yesterday. We should figure this out with something smaller first, but I think this should be the first 'real world' target!

Another one could be Climsim
