[Test] Validates data deletion on EC volume

Test Steps:
1. Create a volume, start and mount it
2. Create directories and files
3. Rename, change permissions of files
4. Create hardlink and soflink and different types of IO's
5. Delete all the data
6. Check no heals are pending
7. Check al bricks are empty
