    @DaanHoogland Thanks for reviewing the code. On MS shutdown/restart the incomplete job
entry will always get marked as cancelled in DB.
    You are right that an async job might continue to run even after MS shutdown. For e.g.
MS is stopped in middle of deploy VM operation. If the command to deploy VM has reached HV
before MS stop, then it will get started. The DB will be synced to correct state based on
vm sync once the MS is started again.
    For volume and other operations (snapshot etc.), there is no recovery in these scenarios.
Something like storage sync needs to be implemented which can update DB state based on the
actual content/state of primary and secondary storages.
