Add automated Cloud Build CI workflow and test runner script for high-bandwidth GCS DirectPath read microbenchmarks against rapid zonal buckets. - Add benchmarks-cloudbuild.yaml to orchestrate VM lifecycle and private SSH runs. - Add run_benchmark_tests.sh for VM environment setup and pytest execution. - Display formatted performance results table directly in Cloud Build logs.

Code Review
This pull request introduces a Cloud Build pipeline (benchmarks-cloudbuild.yaml) and a runner script (run_benchmark_tests.sh) to automate running GCS DirectPath read microbenchmarks on high-bandwidth GCE VMs. The review feedback highlights several critical improvements: implementing a bash trap to guarantee the VM is stopped on early exit, adding defensive type-validation for loaded JSON data to comply with the repository style guide, fixing potential TypeError and ValueError bugs during benchmark result parsing, and verifying that the runtime patching of conftest.py does not fail silently.
… and type validation - Add EXIT trap to ensure standing VM shutdown on failure. - Check SSH connection success and fail if connection times out. - Add target existence validation when patching conftest.py. - Add defensive type validation (isinstance) for parsed JSON results. - Wrap float conversion for network throughput in try-except.

nit: regarding the name of CloudBuild Run - gcs itself has storage , you named it gcs-storage ..., extra storage. - Please remove it. |

…nner - Add _BUCKET_TYPE and _REGIONAL_BUCKET substitutions in benchmarks-cloudbuild.yaml. - Update run_benchmark_tests.sh to export distinct DEFAULT_RAPID_ZONAL_BUCKET and DEFAULT_STANDARD_BUCKET. - Pass BUCKET_TYPE, ZONAL_BUCKET, and REGIONAL_BUCKET to run_benchmark_tests.sh over SSH.
…dencies - Update default benchmark rounds from 2 to 3. - Rename OUT_JSON to OUTPUT_JSON_PATH. - Echo OUTPUT_JSON_PATH and UPLOAD_GCS_PREFIX in runner banner. - Remove redundant google-cloud-kms and duplicate editable pip install commands.
…lone script - Add display_benchmark_results.py to format and display test results. - Invoke display_benchmark_results.py from run_benchmark_tests.sh. - Update Cloud Build Step 4 to reuse display_benchmark_results.py.
