  - bring in updated atmospheric physics with Hack shallow convection.
  - bring in updated atmospheric physics with suite_cam4.xml.

M       cime_config/config_component.xml
M       cime_config/config_compsets.xml
M       cime_config/testdefs/testlist_cam.xml
  - add CAM4 suite and test

M       src/data/registry.xml
  - registry updates for reading necessary fields for Hack shallow convection snapshot test
  - registry updates for use_shfrc and shfrc for future cloud_fraction scheme (persistent)

If there are new failures (compared to the test/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?

If this changes climate describe any run(s) done to evaluate the new
climate in enough detail that it(they) could be reproduced:

Holding as draft until I finish testing and documenting that the CAM4 tests will likely not run because all the snapshot variables are missing and model would crash (#359)

Needs #365 to be merged in first
