Tag name (required for release branches):
Originator(s): @boulderdaze

Description (include the issue title, and the keyword ['closes', 'fixes', 'resolves'] followed by the issue number):

• Build the MUSICA library in CAM-SIMA as part of the Create Terminator and Chapman chemistry configurations #321 to enable the full implementation of MICM and TUV.
• Update the Dockerfiles to include a newer version of ESMF that is the same version used by Derecho, and update the contents to use MUSICA schemes.
• Update the README instructions for downloading submodules.

Describe any changes made to build system:
Added functions to build musica in cime_config/buildlib

Describe any changes made to the namelist: N/A

List any changes to the defaults for the input datasets (e.g. boundary datasets): N/A

List all files eliminated and why: N/A

List all files added and what they do:

List all existing files that have been modified, and describe the changes:

climate in enough detail that it(they) could be reproduced: N/A

It's not shown in the file diff section, so I'm mentioning here that the following path in buildlib doens't exist. Although it's included in the Filepath, the actual directory is missing. This isn't an issue when building the MUSICA or other physics schemes, but I was curious as to why it's included despite not existing.

        # If using the CMEPS/NUOPC coupler, then add additional path:
        if case.get_value("COMP_INTERFACE") == "nuopc":
            paths.append(os.path.join(__CIMEROOT, "src", "drivers",
                                      "nuopc", "nuopc_cap_share"))
        # End if

Hi @boulderdaze, that code was leftover from an earlier version of CAM-SIMA where we had two different CESM coupling infrastructures and had to pick one each time. However, I think now it is just dead code, so feel free to remove it in your PR if you'd like. Thanks for catching it!
