It is not sufficient to set the prefix field on the KubernetesDeploy::StatsD singleton itself, since its value is overridden in the underlying calls to the ::StatsD library, hence the need to pass it in as a custom prefix via the metric_options hash. This is done since KubernetesDeploy may be included as a library and should not change the global StatsD configuration of the importing application.
