    Remove stale chunks when failed to update image to registry

    For image v1 api, the operation of uploading image bits to store and
    the operation of updating image metadata are separaed, so when the
    second operation failed, the image stale chunks will be leaked in store.
    This change added a logic to remove those chunks if an exception
    happenned during the step of image metadata updating. And if
    glance-registry could be reached still, the image status will be changed
    to 'killed', this followed standard glance image status transition.
