I don't know about graceful, but I don't think there is a more

To do this in my current implementation, I get the cell stratum from the DMplex and search through the PetscSF to remove any overlapped (not owned) cells and then reduce over all the ranks to get the total cell count. Is there a more graceful way of doing this already built into DM?
