for datanode metrics to calculate local read rate which is useful to
compare .

> Current dfs context metrics only contains bytesRead ,remoteBytesRead and totalReadTime.We can find that bytesRead= remoteBytesRead +balance remote copyBytesRead+localBytesRead, so we can add localBytesRead and localReadTime to calcute local read rate which is usefu to compate local read rate between short-circuit read and tcp-socket read.
