[Test] Add tests to check remove brick with different options
Test scenarios:
===============
Test case: 1
1. Create a volume, start it and mount it.
2. Create some data on the volume.
3. Run remove-brick start, status and finally commit.
4. Check if there is any data loss or not.
Test case: 2
1. Create a volume, start it and mount it.
2. Create some data on the volume.
3. Run remove-brick with force.
4. Check if bricks are still seen on volume or not
