Tsz-wo Sze updated HDDS-17543:
------------------------------
    Description: 
Currently ReplicationType.CHAINED is unused/not-implemented.  We may use it for 
pipeline V3. 
- For CHAINED pipelines, disallow appendTransaction and applyTransaction in 
ContainerStateMachine.
- For RATIS (i.e. v2) pipelines, disallow stream commands (i.e. stream 
PutBlock).

  was:Currently ReplicationType.CHAINED is unused/not-implemented.  We may use 
it for pipeline V3.  For CHAINED pipelines, do not allow appendTransaction and 
applyTransaction in ContainerStateMachine.
