    Description

      The fix for https://issues.apache.org/jira/browse/MESOS-9964 had to drop the image fetch deduplication that was introduced long ago in https://issues.apache.org/jira/browse/MESOS-3736. We should reintroduce the deduplication back.

      UCR containers pulling the same image at the same time should pull the image only once.
      This deduplication should not prevent killing some of the PROVISIONING containers, and such killing should not interfere with provisioning of other containers.

      I would argue that it is OK for all the containers depending on a single image pull to hang if this single pull hangs.
