> Currrent pipeline has 3 states,  ALLOCATED, OPEN and CLOSED. 
> When create pipeline command is sent out to datanodes from SCM, this pipeline is marked as ALLOCATED in SCM.  Once SCM received all 3 datanodes confirmation of pipelinee creation, SCM will change pipeline's state from ALLOCATED to OPEN.  
> Close pipeline process is similar.  Add a new CLOSING state to pipeline. When close pipeline command is sent out to datanodes, pipeline will be marked as CLOSING.  When all 3 datanode confirmed,  change pipeline state from CLOSING to CLOSED.
