Test rocotoboot dryrun

[TerrenceMcGuinness-NOAA]

Force CI pipelines to use local Rocoto build with dryrun feature

Summary

Implements temporary changes to force all CI/CD pipelines to use a local build of Rocoto with the dryrun feature for comprehensive stress testing across all HPC platforms. Uses configurable platform-specific paths for role account flexibility.

Resolves #4220

Changes Made

• CI Pipeline Templates: Added configurable PATH override using platform-specific settings
• Platform Configurations: Added system-specific settings section to all platform config files
• CTest Framework: Updated execute.sh.in to use standard rocotoboot --dryrun instead of custom binary
• Comprehensive Coverage: Affects build processes, experiment runs, and CTest execution

Files Modified

• .gitlab-ci.yml - Build template with configurable PATH override
• dev/ci/gitlab-ci-cases.yml - Experiment run template with configurable PATH override
• dev/ci/gitlab-ci-ctests.yml - CTest template with configurable PATH override
• dev/ctests/scripts/execute.sh.in - Standard rocotoboot command usage
• dev/ci/platforms/config.* - Added system-specific settings sections (7 files)

Technical Approach

Uses configurable platform-specific paths from role account settings:

# In platform config files
export UTILS_PATH="/path/to/role/account/utils"
export ROCOTO_TEST_PATH="${TEST_UTILS_PATH}/Rocoto/bin"

# In CI templates
if [[ -n "${ROCOTO_TEST_PATH:-}" && -d "${ROCOTO_TEST_PATH}" ]]; then
  export PATH="${ROCOTO_TEST_PATH}:$PATH"
fi

NOTE: Draft PR until all local Rocoto installs are in place and paths above are updated appropriately

Platform Configuration

Added "System-specific settings" section to all platform configs with:

• UTILS_PATH - Base path for role account utilities
• ROCOTO_TEST_PATH - Custom Rocoto build location
• TODO placeholders for actual role account paths per machine

Testing Strategy

• Multi-platform validation across hera, gaeac6, orion, hercules, ursa, and wcoss2
• Full pipeline coverage including builds, experiments, and CTests
• Stress testing with dryrun feature under production CI loads
• Graceful fallback to system Rocoto if custom path not available

Rollback Plan

These are temporary changes designed for easy removal once upstream Rocoto PR is merged:

1. Remove the PATH override sections from CI templates
2. Remove the system-specific settings sections from platform configs

Acceptance Criteria

• All CI pipelines use configurable Rocoto build path per platform
• Dryrun feature accessible for stress testing
• Platform-specific role account path flexibility
• Changes are easily reversible
• Graceful fallback to system Rocoto
• No disruption to existing workflow functionality

Probably want to revert this to fv3-cpu before merging. Fine for testing.
