Implement constituents infrastructure in analytic IC routines

[nusbaume]

Originator(s): nusbaume, adamrher

Summary:

Adds in the subroutine/function hooks needed for the analytic ICs to properly interact with the CCPP constituents object. This PR also contains some bug fixes for the air composition and SE dycore dynamics-physics coupling routines that were found via testing with the FKESSLER and FHS94 compsets. Finally, this PR also includes some slight cleanup of the use of the water vapor constituent standard name within the core CAM-SIMA host code.

Fixes #287

If there are new failures (compare to the existing-test-failures.txt file),
have them OK'd by the gatekeeper, note them here, and add them to the file.
If there are baseline differences, include the test and the reason for the
diff. What is the nature of the change? Roundoff?

derecho/intel/aux_sima: All Pass

derecho/gnu/aux_sima: All Pass

Looks good to me. I think I understand how you're using the new constituent infrastructure to get indices and get defaults constituent values in these ic_xxx.F90 modules. But I did have a question below about what exactly was wrong with the FKESSLER compset, and how this fixes it.

two small things!

looks good to me!
