Description of problem:

restart vdsm when VmReplicateDiskFinishVDSCommand is run. 
the engine rolls back on the LSM but does not send DeleteImage which leaves the image and snapshot in both domains. 
this will cause several issues such as, if I decided to remove the vm and import the back up from the export domain I will not be able to do that since we have left over images which user can only clean with gss. 

Version-Release number of selected component (if applicable):

sf17.1

How reproducible:

100%

Steps to Reproduce:
1. create a vm from template on iscsi storage and run it on hsm host
2. restart vdsm on spm when VmReplicateDiskFinishVDSCommand is run 
3. shut down the vm
4. export the vm
5. remove the vm
6. import the vm 

Actual results:

engine rolls back on the LSM but does not send DeleteImage 

Expected results:

if we decide to roll back we should remove images in the target
if we decide not to roll back (since the sync image completed and the only step after that is delete image) we should delete the images from the source. 

USER IMPACT: in this case, I can't import the vm back to the setup after deleting it.
