Title: Fix backup object/image state during image backup

Changed state transition for backup object and image resources while image backup is performed.

Originally the state diagram was:
init -> creating -> available

Add "pending" state by this change:
init -> pending -> creating -> available

Backup operation is a long running job. it sometime takes long time until the hva becomes ready to start the backup job. pending state represents those waiting jobs on the hva.
