* Interface to consume metrics produced by the IDrm/ICrypto

* To use with IDrm:
* drm->exportMetrics(&consumer);
*
* IDrmMetricsConsumer::consumeFrameworkMetrics &
* IDrmMetricsConsumer::consumeHidlMetrics implementations
* would each be invoked once per call to IDrm::exportMetrics.
* |consumeFrameworkMetrics| would be called for plugin-agnostic

*
* To use with ICrypto:
* crypto->exportMetrics(&consumer);
*
* IDrmMetricsConsumer::consumeHidlMetrics implementation
* would each be invoked once per call to ICrypto::exportMetrics.
* ICrypto metrics are plugin agnostic.

* ----------------------------------------
*
* For an example implementation of IDrmMetricsConsumer, please
* see DrmMetricsConsumer. DrmMetricsConsumer consumes IDrm/ICrypto
* metrics and saves the metrics to a PersistableBundle.
