> Currently we only support instantiating {{MetricReporters}} via reflection, forcing us (and implementees) to deal with numerous downsides such as non-final fields (resources can only be acquired in open()), frustrating test setup (options must always be encoded in a  {{Configuration}}, and requiring non-arg constructors.
> Factories are a more appropriate way of dealing with this, and as such we should add support for it. Existing reporters can be ported to this mechanism without affecting users.
