Failed to delete snapshot copied to Staging storage during snapshot creation.
During snapshot creation process snapshot will be copied to Staging storage and
from there to S3. Once the snapshot is backed up to S3 CS tries to delete the
snapshot from the staging storage.
Steps to Reproduce:
=================
1.Bring up CS with kvm cluster using S3 for Secondary, NFS for staging and
Local for Primary storage
2. Deploy guest vm with root and data disk
3.Take snapshot of the data disk
Observations:
==========
After snapshot is backed up CS sends deleteCommand to delete the snapshot from
staging storge.
