Release/public v2 gaea update

[natalie-perlin]

DESCRIPTION OF CHANGES:

Changes to this SRW release/public-v2 branch are specific to Gaea, and reflect the recent updates to the Lmod/8.7.12, miniconda3/4.12.0, and the hpc-stack modules built with the updated Lmod and miniconda. All these packages and the module manager have been installed under the role.epic account, maintained by EPIC, and in a following common space on Gaea:
/lustre/f2/dev/wpo/role.epic/contrib/
(also linked as /lustre/f2/dev/role.epic/contrib/)

These updates were found to be needed to address missing python packages in existing regional_workflow conda environments, when python plotting routines were used to generate basic plots of the model results.

The changes are related to Gaea only, and their sole purpose is to initialize Lmod properly (which is not installed system-wide on Gaea), and update the paths of the modules.

The files in the SRW repo that were updated, under the ./ufs-srweather-app/ main directory:

./etc/lmod-setup.sh, lmod_setup.csh
./modulefiles/build_gaea_intel
./modulefiles/wflow_gaea

Running the SRW also requred corresponding updates to the regional_workflow repository (yet unmerged, release/public-v2 branch), for which the PR-380 has been created in that repository:
PR-380

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update

TESTS CONDUCTED:

The test has been done on Gaea, to build the SRW and to run a workflow using rocoto and crontab, or the following test case from the comprehensive tests suite:
grid_RRFS_CONUScompact_25km_ics_FV3GFS_lbcs_FV3GFS_suite_GFS_v16.

Because of the dependency of the PR-380 in the regional_workflow repo, temporary modifications to the Externals.cfs in the tested code have been made to use the following regional_workflow repository and branch:

[regional_workflow]
protocol = git
#repo_url = https://github.com/ufs-community/regional_workflow
repo_url = https://github.com/natalie-perlin/regional_workflow
# Specify either a branch name or a hash but not both.
branch = release/public-v2-gaea-update
local_path = regional_workflow
required = True
...

The test intended to provide the concept of loading the new Lmod, modules and packages properly, building the SRW code, and a functional workflow that launches and successfully completes the test.

Location of the test code built and launched on Gaea, under EPIC account:
/lustre/f2/dev/wpo/role.epic/sandbox/SRW/ufs-srw-pub-v2-update/

A corresponding test directory on Gaea is the following:
/lustre/f2/dev/wpo/role.epic/sandbox/SRW/expt_dirs/grid_RRFS_CONUScompact_25km_ics_FV3GFS_lbcs_FV3GFS_suite_GFS_v16

@natalie-perlin I am able to checkout regional workflow with manage_externals and build your PR on gaea applying it to release/public-v2 branch so will approve! Originally I encountered the issue you mentioned with nemsio library when I applied the PR on top of develop by mistake.
