> Currently, pipeline creation and destroy are synchronous operations. SCM directly connect
to each datanode of the pipeline through gRPC channel to 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.
