Switched multi-threads testing from iperf3 to iperf
Switched multi-threads testing from iperf3 to iperf because the
iperf3 was not designed for the multiple threads, see [1] and [2].
So, iperf (v2) will be used for measuring tests with -P option.
Made the number of threads as an configurable option (10 by default).
* installing iperf package
* allowing 5001 port
* starting iperf as well as iperf3 at VMs
* added 'multiple_threads_number' option (10 by default)
* added details which tool was used (iperf3 or iperf) in the final table
* changed the default image from Ubuntu18 to Ubuntu20
