Key differences from calling IPerf3.run():417            - only uses the IPerf3 objects as containers418            - uses subprocess to run iperf3 with the given arguments419            - as a result, only picks some arguments that are expected to exist420              and ignores others421        This is done to enable multiple instances to run concurrently in422        threads without worrying about race conditions on stdout, as the iperf3423        module's run() will reroute stdout to a private pipe. To avoid this, we424        use subprocess to give each iperf run its own private pipe. The only425        other option is to fork each child iperf into its own subprocess, which426        is not too different from this implementation....Learn to execute automation testing from scratch with LambdaTest Learning Hub.
