[Slurm] Collect more data for Slurm nodes

[podkidyshev]

Summary

Collect more info from Slurm nodes

According to diff in src/cloudai/systems/slurm/slurm_metadata.py, added data is:

• MetadataSystem -> gpu_count, gpu_inventory, and cpu_vendor
• MetadataCUDA -> nvidia_driver_version, cuda_toolkit_version
• MetadataNetwork -> nic_count, nic_inventory, hca_firmware_versions, doca_host_version

Test Plan

• Automated CI
• Manual runs on a few internal clusters
  • doca_host_version remained untested as I don't have access to a cluster where related HW is available

Additional Notes

• Added internal ticket to disable slurm metadata collection (e.g. during large DSE jobs)

📝 Walkthrough

Walkthrough

The change expands Slurm metadata collection, adds optional metadata fields, and separates container runtime metadata from host metadata. Generated sbatch references and runner tests validate non-MPI execution, host output appending, and updated output paths.

Changes

Slurm metadata collection

Layer / File(s)	Summary
Metadata collection and data contracts src/cloudai/systems/slurm/slurm-metadata.sh, src/cloudai/systems/slurm/slurm_metadata.py	The script collects expanded system, GPU, CPU, network, firmware, DOCA, OFED, libfabric, MPI, CUDA, and driver metadata. Models define defaulted fields for optional GPU, CPU, CUDA, and network values.
Runtime and host command generation src/cloudai/systems/slurm/slurm_command_gen_strategy.py	_metadata_cmd generates separate non-MPI commands for container runtime metadata and host metadata. Host output uses append mode and the installation-path script.
Generated scripts and test expectations tests/ref_data/*.sbatch, tests/test_single_sbatch_runner.py	Reference sbatch files and runner tests expect separate runtime and host metadata commands, explicit task placement, non-MPI execution, host append mode, and additional output paths.

Estimated code review effort: 3 (Moderate) | ~30 minutes

Merge Risk: 🔵 Low · up to cab07

The Slurm metadata change may report an incorrect libfabric version on some systems, reducing metadata accuracy. The PR is otherwise mergeable with explicit owner awareness and a follow-up parser fix plus regression test.

version token from fi_info --version output, including formats such as fi_info:
1.20.0, without requiring a libfabric label; preserve the existing null fallback
when fi_info is unavailable or no version token is found.

- Around line 22-24: Update the version parser in the fi_info metadata flow to
first select the version token following “libfabric:” from fi_info output, while
retaining the existing first-version extraction as a fallback for older formats.
Add a regression case covering output where the executable and libfabric
versions differ.
