Exporter is overwriting default locale

[davtorrin]

Exporter is overriding the JVM default locale to US and running applications require ES.
ExporterCall does "Locale.setDefault(Locale.US)" and MetricsStream.printPerformanceMetrics already print metrics in US format.

I'm not sure if exporter needs to modify the default locale, but this may cause an issue in a production environment.

Thanks; as far as I can tell, we do not actually need that line, and I am removing it in a pending commit.

The fix is now in main and will be in the next release
