This class is just used to build and start ZenossMetricsReporter?  Name is confusing as isn't actually a reporter.  It is fine if this builds ZenossMetricsReporter.  With the old setup the user of a zapp just configured what kind of MetricPoster to use by either configuration in the yaml or providing a MetricPoster implementation in the Spring Context. Here we can only create HttpBased ZenossMetricReporters.
