[Test] xml Dump of gluster volume status during rebalance
1. Create a trusted storage pool by peer probing the node 2. Create a distributed-replicated volume 3. Start the volume and fuse mount the volume and start IO 4. Create another replicated volume and start it and stop it 5. Start rebalance on the volume. 6. While rebalance in progress, stop glusterd on one of the nodes in the Trusted Storage pool. 7. Get the status of the volumes with --xml dump Change-Id: I581b7713d7f9bfdd7be00add3244578b84daf94f Signed-off-by: “Milind <“mwaykole@redhat.com”>
