> Metrics to measure sequential reads and random reads separately

> Key: HBASE-4989

> HBase does sequential reads for compactions and positional random reads for
> satisfying user's queries. It would be nice if we can measure their latencies
> separately. It is mostly the random reads that dominate a transactional
> workload.
