### Description of PR
HDFS-17345.
Currently, we have block report send time metrics recorded by blockReports.
We should better add another metric to record block report creating cost
time:
`long brCreateCost = brSendStartTime - brCreateStartTime; `
It is useful for us to measure the perfomance of creating block reports.
