CompositeMetricExporter class

A composite metric exporter that delegates to multiple exporters.

This exporter implements the fan-out pattern, where metrics are exported to multiple backends simultaneously. It forwards all export, flush, and shutdown operations to each of its delegate exporters.

This is useful for scenarios where you want to send metrics to multiple destinations, such as a local console and a remote collector.
