dovetail tool: show progress during executing test cases

JIRA: DOVETAIL-159

1. It takes long time to execute test cases that most of users think it hangs there,
   so a progress is needed to show the test is running.
2. add dynamic progress during execution
3. it' s a fake progress only showing the test is alive,
   not to show the percentage of completion.
