  - Merge "Make loading docker images from tars optional"
  - Make loading docker images from tars optional

    As build server for building Nexus blob can be the same machine as for
    previous download, there's not necessary to load all docker images if
    they are already in local registry - therefore this patch makes the
    loading of the images from tarballs as an option and by default will use
    images directly from local registry
