Add logging/recording options to test harness

Add options to QSR test harness to log or record the actual events into a Python script file.

So that the generated Python script file can be used as such for the regression testing when it plays back the events. 

There could be option to include either or both:

1) human readable event and used parameters

• This is useful for logic documentation and debugging

2) constructed message for automatic sending

• This will save blood and tears in testing

3) in case both are included, then #1 could be added as comment lines in the script. And there could be an option for printing out those when running the script. 

Nice to have things:

• add pause between the messages, so that user can see whats happening
• add some default delay between the message, so those are not sent within the same millisecond so that the system has time to process those
• add wait for user input (interactive mode at selected points)
