> After storage cleanup still see the snapshot image oin the secondary storage snapshot
folder for the failure snapshots 
> In this case : next hourly snapshot was successful but previous snapshot was stuck in
> Steps: 
> *************** 
> 1.Deploy a VM and set concurrent.snapshots.threshold.per host to 2 
> 2.Once its successful,schedule the recurring snapshots hourly on the root volume and
also perform snapshot on other instance volumes 
> 3.configure the storage.cleanup.interval to 150 and restart the cloud-management service
while hourly snapshot on root volume is in progress 
> 4.check the secondary storage snapshot folder 
> 5. after few hours,delete all the created snapshots from Cloudstack and check the storage
cleanup thread cleansup all the snapshots form the snapshot folder or not. 
> Actual result: 
> step4:snapshots job failed and secondary storage has copied image file and database shows
snapshot job status as "Backing UP" 
> next hourly snapshot was successful. 
> Step5: 
> It cleans all the successful hourly snapshot images except the failed snapshot image
> Expected result: 
> ****************** 
> Storage GC should clean all image files exists in the snapshot folder when we delete
the all the snapshots from Cloud stack. 
> also when previous hourly snapshot stuck in backing up state ,the next hourly snapshot
is successful,Cloudstack should intelligent enough to update the status of failure jobs properly.
