> HDDS-242 provides a new class ContainerReportHandler which could handle the ContainerReports
from the SCMHeartbeatDispatchere.
> HDDS-228 introduces a new map to store the container -> datanode[] mapping
> HDDS-199 implements the ReplicationManager which could send commands to the datanodes
to copy the datanode.
> To wire all these components, we need to put implementation to the ContainerReportHandler
(created in HDDS-242).
> The ContainerReportHandler should process the new ContainerReportForDatanode events,
update the containerStateMap and node2ContainerMap and calculate the missing/duplicate containers
and send the ReplicateCommand to the ReplicateManager.
