Sanjeev N reopened CLOUDSTACK-2583:
-----------------------------------
Verified this issue with latest build. Now the snapshot creation is successful
but the location where CS stores the snapshot in S3 is different from the path
it specifies in snapshot_store_ref table.
Because of this path mismatch volume and template creation fails from the
snapshot. So the snapshot is of no use.
