I think I'd rather wait until we actually have a need for this before adding it

@liggitt RealFIFO needs to expose metrics, so a MetricsProvider needs to be added to RealFIFOOptions.

I think we need to add options for RealFIFO.

The informer and reflector provider should probably be exposed in their respective options to allow consumers to override the metrics.
