Description

Currently when creating new metrics we use @Metric annotation for registering the MutableMetric i.e

@Metric
private MutableInt foobarMetricCount

However,  there's no support for registering MutableQuantiles via Metric annotation, hence creating this Jira to register MutableQuantiles via Metric annotation. 

Example:

 

@Metric(about = "async PUT entities latency", valueName = "latency", interval = 10)
private MutableQuantiles foobarAsyncLatency;
