This change add pipline configuration support to gether per device rate metrics for instance. The per device rate metrics for instances is transform from the metrics of per devices for instances by adding metrics to disk_pipline in pipline cfg. These metrics will be independent of the support of per devices rate metrics provided by inspector. This thange will add the following metrics: - "disk.device.read.bytes.rate" - "disk.device.read.requests.rate" - "disk.device.write.bytes.rate" - "disk.device.write.requests.rate" Change-Id: I908ab40cc77966238944060e33603c5f4c440634
