Title: Fix issue when hva fails ocassionaly due to race condition of OS resources.

Hva got concurrency for backup image and run local store instance operations. Running local store operaion became to fail sometime when multiple same jobs run.

I split the run local store job to two parts:
1. Copy image file in the queue allows concurrency.
2. Later stages, attach loop dev or start instance, are executed in sequencial queue.

Hope the change will reduce the error rate from the load test for run local store instance.
