[object_store_Refactor] Snapshots removed field is not set after successful
deletion of the snapshot
After deleting snapshot from CS , snpashot's removed filed is not set in
snapshots table.
Steps to Reproduce:
================
1.Bring up CS with xen cluster.
2.Deploy guest vm with default cent of template
3.Take snapshot on the guest vms root disk
4.Set storage.cleanup.interval to a small value say 60 sec. and restart
management server
5.After snapshot comes to Backedup state delete it from CS
Observations:
===========
snpashot status was set to Destroyed in snapshots table after deleting the
snapshot. After storage gc kicked in snapshot was deleted from the secondary
storage. However snapshot entry's removed filed is not set.
