LuyaoZhong 255b3f2f91 Track error migrations in resource tracker 
If rollback_live_migration failed, the migration status is set to
'error', and there might me some resource not be cleaned up like vpmem
since rollback is not completed. So we propose to track those 'error'
migrations in resource tracker until they are cleaned up by periodic
task '_cleanup_incomplete_migrations'.

So if rollback_live_migration succeeds, we need to set the migration
status to 'failed' which will not be tracked in resource tracker. The
'failed' status is already used for resize to indicated a migration
finishing the cleanup.

'_cleanup_incomplete_migrations' will also handle failed
rollback_live_migration cleanup except for failed resize/revert-resize.

Besides, we introduce a new 'cleanup_lingering_instance_resources' virt
driver interface to handle lingering instance resources cleanup
including vpmem cleanup and whatever we add in the future.
