Review Comment:
I am thinking that if this were a class _name_ then we would be able to set
the value in the runner v2 and then the portable `FnHarness` could instantiate
it with reflection. I guess that doesn't solve the cross-language issue, where
we really need to be config-driven. Is there already a factory for building
tracer providers from configs, maybe as part of otel?
