The old process manager's `Trace` function by default calls `log.Printf` to output "trace" level logs. That's not ideal because by default the trace level logs should not be outputted. In history it didn't cause problems because there was no other call to the process manager before the logger system's initialization. But if there is any package using the process manager before the "Trace" function gets assigned to the logger system's trace function, the process manager will outputs unexpected verbose messages, this behavior is not expected in most cases. Now, the logger system also uses process manager to manage its goroutine contexts, so it's the time to fix the old "trace" behavior: by default, do not output the trace level messages. Fix #24951
