> Two complementary functionalities want to address with this improvement.
> - checkpoint the async jobs. perhaps use current journal to record the all entity manipulation,
For e.g  asyncJob for VM create can have journal like
>      Volume, create, ID   
>      Network, implement, id
>      Nic, prepare, id etc
> - asyncjob management api currently exposes ability to perform query and list async jobs.
There is no api support to cancel a job or restart a job. async job manager can be enhanced
to add pause, cancel, restart the jobs
> A Job pause (pause to nearest checkpoint) and job restart (restart from the last checkpoint),
cancel (rollback from last checkpoint) can be used to help recovering from failures.
