- Added `--max-concurrency` argument to service templates for configuring maximum concurrent requests per worker. - Updated validation logic in `validate_concurrent_requests_per_worker` to handle sync and streaming endpoints. - Modified `get_concurrency_limiter` to check for concurrency settings from environment variables. - Implemented extraction of `concurrent_requests_per_worker` from deployment configurations for autoscaling.

This pull request introduces improvements to how the maximum concurrency per worker is configured, validated, and propagated across the model engine deployment and autoscaling logic. The main changes ensure that the concurrency setting is passed from configuration templates through to runtime, validated for autoscaling safety, and surfaced in resource reporting.
Configuration and Runtime Propagation:
--max-concurrencyargument to the forwarder container command inservice_template_config_map.yaml, allowing per-worker concurrency to be set via environment variable (CONCURRENT_REQUESTS_PER_WORKER). [1] [2] [3] [4]--max-concurrencyas a command-line argument, storing it in the environment for use in concurrency limiter setup.Validation Enhancements:
validate_concurrent_requests_per_workerfunction to check that, for sync/streaming endpoints,per_workeris less than half ofconcurrent_requests_per_workerto prevent autoscaling issues. This validation is now called with the additionalper_workerparameter during endpoint creation and update. [1] [2] [3] [4]Resource Reporting and Autoscaling:
concurrent_requests_per_workervalue from the forwarder container’s command in deployment configs, making it available for autoscaling parameter calculations and resource reporting. [1] [2] [3]These changes collectively improve the robustness and transparency of concurrency configuration and autoscaling for model endpoints.
