  This removes tr_pond_cesm and all code related to it. Now in a CPP UNDEPRECATE_CESMPONDS. This will break CICE. However, all base_suite tests (cheyenne/intel) are bfb. The set_nml.cesmponds option was removed from the testsuite. Note that tr_pond_cesm was also removed from the default icepack_in as well. Documentation has been updated with notes that this is deprecated. The one test that failed is missing baseline.

Are we going to remove the CESM ponds documentation now, later, or just continue to note it's been deprecated in the documentation?

Let’s leave the background doc info for the preliminary deprecation and remove it completely in the final release step.
