Review comment:
You are right. Close pipeline with timely a status confirm will make the
propose more clear.
Given this patch is already too big, I created HDDS-2176, Add new pipeline
state “CLOSING” and new CLOSE_PIPELINE_STATUS command, to track the task.

> Currently, pipeline creation and destroy are synchronous operations. SCM

> create the pipeline to destroy the pipeline.
> This task is to remove the gRPC channel, send pipeline creation and destroy
> action through heartbeat command to each datanode.
