> Currently when creating new metrics we use @Metric annotation for registering the MutableMetric
i.e
> {code:java}
> @Metric
> private MutableInt foobarMetricCount
> {code}
> However,  there's no support for registering MutableQuantiles via Metric annotation,
hence creating this Jira to register MutableQuantiles via Metric annotation. 
> Example:
>  
> {code:java}
> @Metric(about = "async PUT entities latency", valueName = "latency", interval = 10)
> private MutableQuantiles foobarAsyncLatency;
>  
> {code}
>
