> Building on the addition of the {{recordGauge}} method to the {{ProcessSession}} interface, the standard class should be updated with an initial implementation.
> As an incremental approach to implementation, a new framework-level interface should be created to report Gauge records. This interface should form the basis for subsequent implementation that can support optional persistence of Gauge records in the framework. Naming the interface {{ComponentMetricReporter}} captures the general purpose, and opens the possibility for other types of processing metrics to be reported.
> Following the pattern of other framework interfaces, the implementation should be configurable through an application property. The default value should be empty. Subsequent additions to the framework for persistent storage, similar to Counters, can consider additional application properties if needed.
