CCPP v7 public release

[lulinxue]

The CCPP v7 public release is planned for June 2024. This release will include updated physics schemes and suites to be determined with input from the CCPP Physics code management group, updates of the CCPP Framework, and improved/new functionalities of the CCPP SCM (Single Column Model) such as the initialization and forcing from UFS results, the suite simulator, and running physics in single precision.

All suggestions, comments and questions related to this release are welcome!

Some of the major new SCM capabilities planned for this release are:

Suite simulator
Replay (ability to initialize and force from UFS files)
Build system using spack-stack
It is premature to plan a release with the next generation CCPP Framework (aka capgen) at this time. That is a plan for a future release
