----------------------------------

Thanks [~ajayydv] for updating the patch and for the explanation. The patch 
looks good to me.
With this behavior how are we going to differentiate an invalid containerId and 
an open containerId when we make  {{getContainerReplicas}} call? (Note: Open 
containers are also maintained by ContainerStateManager)

> Add the ReplicaMaps to ContainerStateManager

> We need to maintain a list of data nodes in the SCM that tells us where a 
> container is located. This created from the container reports.  The HDDS-175 
> refactored the class to make this separation easy and this JIRA is a followup 
> that keeps a hash table to track this information.
