Description:
==================================
1. Executing VM resize error, and the the dir of inst_base_resize has been
created by `os.rename(inst_base, inst_base_resize)` in the function of
migrate_disk_and_power_off. The function of `_error_out_instance_on_exception`
in _resize_instance just catch exceptions and can not rollback dir.
2. Executing command of `openstack server set` to recover VM status to
active.
3. Executing VM resize error again, and Exception in Sample traceback.
The operation of `os.rename(inst_base, inst_base_resize)` failed because
of the dir of inst_base_resize has console.log.
4. Whether or not execute `self._cleanup_remote_migration` before
`os.rename(inst_base, inst_base_resize)`? Is there any methods to
optimize exception handling in the function of _resize_instance ?
