Bug Description

Currently, Resource Tracker has tracked_instances and tracked_migrations, error migrations and orphan instances not included, but these may also have occupied some resources.So we should track them also. We have already a patch to deal with it. [1]

We expect period task "_cleanup_imcomplete_migrations" can handle the error migrations and set them to 'failed' status after some cleanup works, then the migrations will not be tracked in Resource Tracker.
For orphan instances, there are already some patch doing related works. [2]
before the orthan instances cleanup, we should keep them in resource tracker.
