Test Remove MPICommExecutor from historical_forcing.py

[mxkpp]

This removes usage of MPICommExecutor from historical_forcing.py to test behavior on certain environments.

Additions

Removals

• MPICommExecutor from historical_forcing.py (it is still used in regrid.py).

Changes

Testing

1. I ran a AORC calibration using the RTE image. Speed with -n 2 on a 4-core Workspace for a 10-day calibration using KGE + DDS was comparable, before and after the change. Effects could differ when running longer simulations with different settings, where more instances of forcing cache file interaction may occur.

I edited the description to include a note about before and after performance for a 10-day 2-core AORC calibration ran on a 4-core Workspace.

This looks good, and ready to test on integration.
