=============
DHT: Once remove brick start failed in between Remove brick commit should not be allowed 

Steps:
========
1. Create a distributed volume with three bricks and mount it on client using FUSE
2. From the mount point create lots of directories and one direcotry with 30k files
3. Remove one of the brick form the volume and while re-blance is in progress delete all directories and files from the mount point and due to this remove-brick operation failed 
4.Though remove-brick operation failed remove-commint job is getting succeeded, 

Expected Result:
================
Remove-brick commit should be allowed only when the remove-brick operation job is passed

    glusterd: remove-brick commit should not succeed when migration failed
    
    While remove a brick if the data migration was not successful,
    remove-brick commit should not succeed as this can lead to
    data loss.
