[Dune] Use custom load balancer when loading YaspGrid from DGF file

[Jurgis Pods]

Hi Steffen,

I know, it's a bit over the top. But I have situations where I have 
already constructed a grid and then want to load an old grid from a DGF 
file (together with some saved solution vectors for this old grid). I do 
this to interpolate some data from the old grid to the new grid.
So far (using a sequential UG), this could easily be done using 
DGFParser, and I just thought it would be nicer to keep the same 
workflow for my parallel YaspGrid. But as you said, setting up a 
YaspGrid manually isn't that hard, and actually I already implemented 
it, so nevermind!

I just want to make sure that I have the same grid partitioning that I had at the time of saving the DGF file.
