Get data points for a particular {@link Locator}, {@link Range}, and
{@link Granularity}.

This method is eventually called from Rollup process.

@param locator
@param range
@param gran
@return a {@link MetricData} containing the data points requested
Get data points for a particular { @link Locator } { @link Range } and { @link Granularity } .
