   When there are many DNs, and if any DN is slow in processing. It is 
difficult to identify which DN is having issue unless we check the log deeply 
and can take long time. For fast debug in this PR, metrics are added in SCM per 
datanode to show how many delete command sent to datanode and how many response 
received or timedout. This will help in understand which DN is slow or having 
problem in much efficient way.
