[Test] Checks all types of heal on EC volume

Steps:
1.Create a volume and mount it
2.Create a directory, dir1 and run different types of IO's
3.Create a directory, dir2
4.Bring down redundant bricks
5.Write IO's to directory dir2
6.Create a directory, dir3 and run IO's(read,write,ammend)
7.Bring up bricks
8.Monitor heal
9.Check for data intergrity of dir1
