Please lower the amount of output to the console

The amount of output to the console is too extensive for human. The output is great if the stdout is used as log when tests are run in CI.

It would be much better to have the tool to print by default just things like:
"Testing component XYZ"
"Testing scenario XYZ"
"Starting the server process..."
"Starting the client process..."

On the other hand the possibility to have the full output should be preserved as an option. Also another idea would be to save the full log into a file every time for further inspection.

It looks like this change will require some small changes in python-ptrace as well because it uses python logging module incorrectly. I have a couple of other changes to be done in python-ptrace so I think I will handle those at once.

This has been partially addressed. Keeping open so we finish the work including changes in python-ptrace.
