Add regression test against original cloud chemistry module

[mattldawson]

Adds a set of tests that run the new cloud chemistry modules (cloud_aqueous_chemistry, cloud_utilities, mam_clouds) with input data collected from running CAM with:

./create_newcase --compset QPC6 --res f10_f10_mg37 --case $CASE_DIR --run-unsupported

There are tests against the output collected from CAM and against the original module code run with the collected inputs.

Closes #4

Looks good! I just have a couple questions.

@mattldawson
Does this enable the ability to run a stand-alone test outside of CESM/CAM?
Maybe you can explain the need for all the added code the next aerosol dev meeting.

Hi @fvitt - yes, it does. I added some instructions for running the tests here. This will also allow us to set up a test that ensures the CAM code doesn't diverge from what we put in MICM/CAM-SIMA after we're done refactoring. We can discuss more in the next meeting.
