Replace PIPE-based stdout/stderr capture with direct file output in LoadGenerator.generate_load() to prevent orphaned aiperf child processes from blocking communicate() indefinitely
Add start_new_session=True so os.killpg() can kill the entire process tree on timeout (not just the main process)
Add unit test validating process-group kill on timeout
Fixes DYN-2086
