   > For SafeModeRules, I do modified the HealthyPipelineSafeModeRule a bit. 
Add two properties, one is "hdds.scm.safemode.pipeline.creation" to control 
whether create pipeline in safemode.
   Another is "hdds.scm.safemode.min.pipeline" control the minimum pipeline 
number to exit safe mode when create pipeline in safemode is enabled.
   
   @ChenSammi The problem is safe mode rules are only tracking the old 
pipelines. But since they are listening to OPEN_PIPELINE event any newly 
created pipeline is counted in the rule. So if we are waiting for 50 old 
pipelines and 20 new ones are created, rule would pass if just 30 old pipelines 
are reported. Therefore I think we need a way to separate the old pipelines 
from new ones in the rules.

> 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.
