> Currently ContainerStateMachine sets ContainerCommandRequestProto as state machine data.
This requires converting the ContainerCommandRequestProto to a bytestring which leads to
redundant buffer copy in case of write chunk request. This can be avoided by setting the
chunk data as the state machine data for a log entry in ratis.
