Adding CCPP to coupled system

[junwang-noaa]

This issue is for the ufs-s2s-model pull request:

#7

Add CCPP capability in coupled model

[junwang-noaa]

CCPP will provide 3 CCPP suite files (2 for the two new IPD tests Bin added, one for benchmark 3.1)
s2s will have 2 new tests added besides current 8 RT tests.
Corresponding CCPP test will be created.
Both IPD tests and CCPP tests will be run on REPRO mode, and the results should be identical. An 8 cases 35 day long runs using CCPP PROD will be conducted separately.
IPD tests and REPRO CCPP tests will be droped at the end of transition.

Associated issues:

1. create regression test for two-way wave-atm coupling for a FV3-MOM6-CICE5-WW3 test
2. Make 1 day reg test that matches a benchmark case
3. Set of tests for IPD v CCPP for longer runs that mimic benchmarks
4. Decide CCPP configuration for coupled benchmark 4
5. IPD and CCPP test comparison and drop IPD test in S2S RT

@junwang-noaa Can we close this issue on ufs-s2s-model?
