NodeTracerProvider plugins property

[jaypeeig]

Hello,

I'm doing a POC regarding traces with kafka and I found opentelemetry-instrumentation-kafkajs interesting.
But upon trying, it seems that the plugin property is available in NodeTracerProvider.
https://www.npmjs.com/package/@opentelemetry/sdk-trace-node
https://github.com/aspecto-io/opentelemetry-ext-js/tree/master/packages/instrumentation-kafkajs

Usage Example

Local Error

Is there an example implementation of using it?
I'm keen to understand how is it configured :)
