Description
Since HDDS-398 we can support multiple type of freon tests. But to add more test we need common utilities for generic task.
One of the most important is to provide a reusable Progressbar utility.
Currently the ProgressBar class is part the RandomKeyGenerator. It should be moved out from the class and all the thread start/stop logic should be moved to the ProgressBar.
ProgressBar bar = new ProgressBar(System.out, () -> ... , 200);
bar.start(); // thred should be started herebar.stop(); // thread should be stopped.
