improve runoff distribution

This PR complements GEOS-ESM/GEOS_OceanGridComp#105 to improve the runoff distribution.

@mfmehari, I think OBIO needs to be addressed separately as it also has a DISCHARGE import. I can't do it since I am not running the OBIO model.

@zhaobin74, I think if DISCHARGE is imported at OGCM GC level instead of Ocean GC, it will also work for OBIO.

@mfmehari, unfortunately OGCM GC 's grid is not tripolar and ExtData does not support. There are two ways to get proper runoff to obio:

• do not terminate DISCHARGE import of OPBIO and let ExtData fill it, just like Ocean GC. I am not sure if the two DISCHARGE imports (from Ocean and OBIO) are ok.
• make a connection between OCEAN DISCHARGE export and OBIO DISCHARGE import

@zhaobin74 Ah with "OGCM GC 's grid is not tripolar" it won't work. I will have it imported from ExtData from OBIO GC.

Thanks @mfmehari. Please submit another PR for OBIO GC.
