> Right now in hadoop metrics2, String metrics from method are categorized as 
> tag (v.s. metrics as other number types), this caused later when reporting 
> beans, it will add a prefix "tag." before the metric name.
> It will be cleaner if we have another child inherit MutableMetric for string 
> (maybe MutableText?) thus the String metrics from method can get rid of the 
> tag.
