[Test] Add test to check kill brick with remove brick running
Test case: 1. Create a volume, start it and mount it. 2. Create some data on the volume. 3. Start remove-brick on the volume. 4. When remove-brick is in progress kill brick process of a brick which is being remove. 5. Remove-brick should complete without any failures.
