> Datanode IO (Disk/Network) related operations and instrumentations are currently spilled
in many classes such as DataNode.java, BlockReceiver.java, BlockSender.java, FsDatasetImpl.java,
FsVolumeImpl.java, DirectoryScanner.java, BlockScanner.java, FsDatasetAsyncDiskService.java,
LocalReplica.java, LocalReplicaPipeline.java, Storage.java, etc. 
> This ticket is opened to consolidate IO related operations for easy instrumentation,
metrics collection, logging and trouble shooting.
