> HDDS/Ozone supports Open and Closed containers. In case of specific conditions (container
is full, node is failed) the container will be closed and will be replicated in a different
way. The replication of Open containers are handled with Ratis and PipelineManger.
> The ReplicationManager should handle the replication of the ClosedContainers. The replication
information will be sent as an event (UnderReplicated/OverReplicated). 
> The Replication manager will collect all of the events in a priority queue (to replicate
first the containers where more replica is missing) calculate the destination datanode (first
with a very simple algorithm, later with calculating scatter-width) and send the Copy/Delete
container to the datanode (CommandQueue).
> A CopyCommandWatcher/DeleteCommandWatcher are also included to retry the copy/delete
in case of failure. This is an in-memory structure (based on HDDS-195) which can requeue the
underreplicated/overreplicated events to the prioirity queue unless the confirmation of the
copy/delete command is arrived.
