    Handle images which exist but can't be seen.

    If the master and the slave glance have different permissions, you
    can end up with a 409 exception at upload. For example:

     - the image is visible to the replication user on the master
     - the image is present on the slave, but not visible to the
       replication user

    The replicator checks for the existance of the image by doing a HEAD
    on http://server:port/v1/images/uuid and gets a 404 back. It therefore
    decides the image doesn't exist and that it should be replicated. It
    does a POST for that URL, and gets a 409 back saying that UUID is
    already in use.

    Resolves bug 1030396.
