    clusters using credentials to provide permission to access the datasets.
    
    * Add authority_urn to the images table, which is the urn of the origin
      dataset (similar to the slice urn, the Portal mints a credential in
      its namespace, so that the Portal always has permission to do anything
      it wants to the dataset at the remote cluster).
    
    * Add slot to the apt_datasets table to store a credential from the
      cluster where the dataset lives. This credential gives the owner
      permission to download the dataset, which the portal will delegate to
      any cluster that might need to get that dataset.
