> Issue tldr:
> 1. AM gets extra containers from the RM which it saves for later use
> 2. When the container that we saved in step1 dies, the AM on receiving this callback does nothing about it.
> 3. Later, when we are looking for a container to use - we pick up the dead container that we saved and did not clean up (step 1&2) and launch a container. 
> 4. Now, if this launched container ever dies - the RM will never notify the AM about it since it see's it as a duplicate (step 2)
> 5. Job is left without the container rescheduled and will need to be restarted.
