Feature 1694 s2s subgroups

[georgemccabe]

Change Summary

• Split s2s use cases into 3 groups (s2s, s2s_mid_lat, and s2s_mjo) to reduce the size of the input data sets to prevent GHA environment disk space issues
• Added logic recommended by GitHub developers to reduce disk size by removing files that are not needed by us, i.e. android dev tools
• Renamed convection_allowing_models category to short_range per Change all references from Convection Allowing Models to Short Range #947
• Modified logic to made repository rename from METdatadb to METdataio
• Changed exit code for diff tests so that it is easier to determine whether a use case group has failed due to errors in a use case (exit 1) or differences in the output (exit 2)

Pull Request Testing

• Describe testing already performed for these changes:
  

Ensured all use cases ran successfully in automated tests

• Recommend testing for the reviewer(s) to perform, including the location of input datasets, and any additional instructions:
  

• Ensure all failures in automated tests are due to differences because the use case names and numbers have changed.
• Verify documentation of moved/renamed use cases are correct and formatted properly
• Check output files that flagged differences and ensure that the output is correct.
  • short_range use cases will correspond to the same number as the old convection_allowing_models equivalent
  • Most of the s2s use case numbers has shifted and some have been moved to new groups. The output should not change except that input/output directories that referenced s2s will now reference the new group names s2s_mid_lat and s2s_mjo for cases moved to those groups
• Optionally run use cases that have changed locally

• Do these changes include sufficient documentation updates, ensuring that no errors or warnings exist in the build of the documentation? [Yes]

• Do these changes include sufficient testing updates? [Yes]

• Will this PR result in changes to the test suite? [Yes]
  
  If yes, describe the new output and/or changes to the existing output:
  
  See above. Diffs will be shown in many use cases because they were renamed/renumbered. The actual output of these use cases should not differ.

Need to add in "short_range" to replace the "convection_allowing_models".

[georgemccabe]

You are looking at the "before" text. This change is removing convection_allowing_models and adding short_range below.

[CPKalb]

Output from RMM, OMI, blocking, and weather regime match what they were prior to the change, so this looks good on my end. We may want to uncover the settings to avoid overlapping documentation in the future

[j-opatz]

Change over for naming and new s2s categories looks to be all set. Documentation looks correct, and any missed references to convection allowing models at least shouldn't break the documentation.
