    Delete orphaned instance files from compute nodes
    
    While resizing/revert-resizing instance, if instance gets deleted
    in between, then instance files remains either on the source or
    destination compute node.
    
    To address this issue, added a new periodic task
    '_cleanup_incomplete_migrations' which takes care of deleting
    instance files from source/destination compute nodes and then
    mark migration record as failed so that it doesn't appear again
    in the next periodic task run.
