app.UseMetricsReporting blocks on RunReports

[alhardy]

Calling run reports blocks waiting for the reporter thread to finish but this is long running for the lifetime of the app.

lifetime.ApplicationStarted.Register(
                () =>
                {
                    reporter.RunReports(metrics, appLifetime.ApplicationStopping);
                });
