Introduces tests/ci_perf/ — a pytest plugin + CLI tooling that captures
prefill_time, decode_perf, onnx_size_bytes and qpc_size_bytes per model on
every QAIC CI stage, persists them to a JSON baseline DB on the CI host, and
adds two new Jenkins stages:
- Perf Comparison: compares current PR metrics against the baseline DB using
a configurable percentage threshold (default 5%) and blocks the PR on
regression.
- Update Perf Baseline: runs only on the main branch and atomically updates
the baseline DB with the current run's values.
Key design decisions:
- Hardware-keyed DB prevents false failures across different NSP configurations.
- Composite key (model::bs=N::seq=N::decode=X) ensures same model with
different inference configs never collide in the DB.
- Sizes are optional — inference-only tests omit onnx_path/qpc_path and the
null values are stored but never compared.
- xdist-aware plugin merges worker records via pytest_testnodedown.
- First-run grace: new models not yet in the DB are SKIPped, not failed.
