Use CpGrid::loadBalance to distribute the field properties.

The created data handle for the communication could in theory be used
with other DUNE grids, too. In reality we will need to merge with the
handle that ALUGrid already uses to communicate the cartesian indices.

This PR gets rid of using the get_global_(double|int) method in
ParallelEclipseState and reduces the amount of boilerplate code there.
