rbd driver cannot delete residual image from ceph in some cases
RBD supports a mechanism that when add image operation failed, rollback
operation will be triggered (delete residual image if it was created).
When uploading image through glance api failed, however, the incomplete
image has not been taken snapshot yet, then rollback operation do unprotect
snap will throw exception "rbd.ImageNotFound".
This exception will lead to the code relating to remove residual image
from ceph, which is the true purpose of rollback, has been skipped.
Thus, re-uploading image will failed using the same image id due to above
reason (residual image already exists) & residual image need to be deleted
manually from ceph.
