Sometimes we want to detect the hotspot of a cluster, for example, hot scanned tablet, hot wrote tablet, but we have no insight about tablets in the cluster. This patch introduce tablet level metrics to help to achieve this object, now support 4 metrics on tablets: `query_scan_bytes `, `query_scan_rows `, `flush_bytes `, `flush_count `. However, one BE may holds hundreds of thousands of tablets, so I add a parameter for the metrics HTTP request, and not return tablet level metrics by default.
