This is to fetch metric values as a time series within a specific time range.
For instance, if an application runs from 11:00 am to 11:45 am and user wants
to see a specific metric as a time series from 11:20 am to 11:40 am only (maybe
to debug some issue). This was the use case I had in mind.
We can use Scan#setColumnFamilyTimeRange which I think is available from HBase
1.2 onwards. I have linked the relevant HBase JIRA here as well.
