    Retry failed instance file deletes.
    
    This change adds a new column to the instances table named "reaped".
    This column indicates that the instance files on disk have been
    deleted for that instance, assuming that the virt driver you are
    using supports that feature (which only libvirt does for now).
    
    Then the flag instance_delete_interval specifies how often to
    retry deletes. The default is five minutes. A value of zero will
    disable retries.
    
    This change is done in this way because reaping will become a more
    generic concept in the next patch.
    
    DocImpact: the following new flags are added...
    
     - instance_delete_interval: how often to try to clean up instance
       files
    
     - maximum_instance_delete_attempts: how many attempts to have before
       giving up
