klog v2 defaults -logtostderr to true, which silently ignores -stderrthreshold — all log levels go to stderr unconditionally. This has been an open issue since 2020 (kubernetes/klog#212). klog v2.140.0 introduced a fix behind an opt-in flag (legacy_stderr_threshold_behavior). This commit bumps klog to v2.140.0 and enables the fix in all 4 command entry points (device-scheduler, device-monitor, device-webhook, device-plugin) so that -stderrthreshold is honored, while preserving the current default behavior (stderrthreshold=INFO means all logs still go to stderr unless the user overrides it on the command line).
