> As [~ljain] mentioned during the review of HDDS-245 SCMClientProtocolServer.getContainerWithPipeline
doesn't return with good data for closed containers. For closed containers we are maintaining
the datanodes for a containerId in the ContainerStateMap.contReplicaMap. We need to create
fake Pipeline object on-request and return it for the client to locate the right datanodes
to download data.
