`capgen.py` progress

Working on PR addressing #346 (ignore missing optional arguments)
Need to discuss requirements for host model to communicate threading information to CCPP suites
- Suite needs horizontal_loop_begin and horizontal_loop_end
- Chunked data turns into a flat array for suite-created data
- UFS provides information on number of blocks, blocksizes, ... - information is scattered (some in host model, some in ccpp-framework)
  - what we have now might work as it is
- Host model most either provide these details when using blocked data structures, or horizontal_loop_begin/horizontal_loop_end when using flat data structures
- UFS only does "no blocks at all" (init/final) phases, or the same blocks throughout the run
- CCPP has a requirement to be able to use different block sizes for different parts of the physics

Transition to `capgen.py`

Still working on the last IPD cleanup steps, and updating/simplifying the codebase
Is it still realistic to target a transition to capgen.py by the end of February?
