network_bandwidth_test log option doesn't write log unless --log-level=debug is also specified

[Jeff Lane ]

When running network_bandwidth_test, there are two log related options.

--log sets a log file to output results to
--log-level sets the logging level

however, when using --log, logging info, including INFO level messages are ONLY written to the specified log file when --log-level is also set to debug.

So this should be changed to where --log implies DEBUG level output, or fixed so that the appropriate messages are actually written to the log file when the script runs.

Steps to reproduce:

- From the checkbox trunk run:
sudo PYTHONPATH=. scripts/network_bandwidth_test --log=/tmp/something

Expected result: Something in the logfile
Actual result: Nothing in the logfile

Setting to Triaged, work to do: make it so that, if --log is specified, log-level defaults to something useful.e

This script got removed by Sylvain in commit 18f79d91e4376193287b980c60452b9a6696d221 on Jul 3rd 2017.

And I consider the removal to be the ultimate fix!
