Release/public v2 gaea update

[natalie-perlin]

This update is for backward compatibility with the SRW release/public-v2 branch of the SRW App,
https://github.com/ufs-community/ufs-srweather-app.git.

Changes are made to reflect updates in Lmod/8.7.12, miniconda3, and the hpc-stack on Gaea NOAA HPC system, installed under epic.role account in /lustre/f2/dev/wpo/role.epic/contrib/ space, and maintained by EPIC.

** FILES CHANGED

The following scripts have been changed under the ./regional_workflow/ base directory:

./ush/machine/gaea.sh
./ush/load_modules_run_task.sh (contribution of @EdwardSnyder-NOAA )
./modulefiles/module-setup.sh.inc
./modulefiles/module-setup.csh.inc
./modulefiles/tasks/gaea/make_grid.local, get_extrn_ics.local, get_extrn_lbcs.local, make_orog.local, make_sfc_climo.local, make_ics.local, make_lbcs.local, run_fcst.local, run_post.local (contribution of @EdwardSnyder-NOAA )

** TESTING PERFORMED

The updated repository has been tested on Gaea as a part of the SRW release/public-v2 branch,
by specifying the url for the regional_workflow in the Externals.cfg as following:

[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
...

Additional files in the SRW release/public-v2 branch were modified to sync the updated Lmod/8.7.12, miniconda3/4.12.0 and the hpc-stack initialization, under the main SRW directory, such as ./ufs-srweather-app/:

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

These updates of the SRW release/public-v2 branch are being prepared as a separate PR into the
https://github.com/ufs-community/ufs-srweather-app.git, to correspond the current changes to the regional_workflow repo, release/public-v2 branch.

The SRW has been build, and a test case grid_RRFS_CONUScompact_25km_ics_FV3GFS_lbcs_FV3GFS_suite_GFS_v16 from the comprehensive test suite has been run using the rocoto and crontab table. The following stages have been successfully completed:
make_grid
make_orog
make_sfc_climo
get_extrn_ics
get_extrn_lbcs
make_ics
make_lbcs
run_fcst
run_post_f001 - run_post_f006.

[EdwardSnyder-NOAA]

The get_extrn_lbcs.local file under gaea (modulefiles/tasks/get_extrn_lbcs.local) needs to removed. It should go under: modulefiles/tasks/gaea/get_extrn_lbcs.local, which you have already.

I tested it on Hera, and it works fine.

[natalie-perlin]

Removed a redundant module placed under ./regional_workflow/modulefiles/tasks/

@EdwardSnyder-NOAA - the repo has been updated, a redundant file has been removed!
