virtio_console: python3 issue fix

hotplug_mem: add new case to hotplug memory to different nodes

- Update iperf2 version to iperf-2.0.12
- Add parameter "timeout" into `t.join()`

1. iperf-2.0.5 failed to compile on gcc 6.3 or higher version.
In order to support RHEL8, update it.
2. Add the "timeout" parameter. When interrupting iperf, if
the client task in the guest is not completed, the host iperf
server will wait threads to complete. So add it to avoid
unexpected situations, otherwise the work will always hang.
