[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 Change-Id: I2cfd324093c0a835811a682accab8fb0a19551cb Signed-off-by: kshithijiyer <kshithij.ki@gmail.com>
