Associate the specified value with the specified data key in the description of the metric having the specified category and metricName. Optionally specify a metrics manager to configure. If manager is 0, configure the default metrics manager; if manager is 0 and the default metrics manager has not been initialized, this method has no effect. If a MetricId does not exist for the category and metricName, create one and add it to the metric registry of the indicated metrics manager. The behavior is undefined unless key was previously created for the indicated metrics manager's metrics registry (e.g., by calling createUserDataKey). Note that this method allows clients of balm to associate (opaque) application-specific information with a metric.
