> When using PrometheusReportingTask, metrics of removed/renamed components
> continues to remain after removing/renaming them completely in the NiFi UI.
> This is supposed to happen because PrometheusReportingTask adds an
> incremental difference into the Prometheus' collector. To deal with it, we
> could clear all collectors before returning the metrics.
