> Noticed something while looking at MBeans; some metric names are capitalized while others aren't. This has the unwanted property of changing the metric names sorting. For example:
> Namespace_default_table_t_region_0122d54a90c9dc191857daf11e8a047d_metric_scanNext_num_ops
> namespace_default_table_t_region_0122d54a90c9dc191857daf11e8a047d_metric_appendCount
> The reason for this is that {{MutableHistogram}} uses {{StringUtils.capitalize()}} on the metrics name (as create by {{MetricsRegionSourceImpl}} with "namespace_").
> I'm not sure what the intent was with capitalization, but either way it's a simple fix. [~eclark]?
