Add metrics monitoring for runtime environments

Feature Request

Is your feature request related to a problem?

The current opentelemetry-demo app does not include some metrics monitoring or not sufficient metrics monitoring for runtime environments such as node.js and golang.

Describe the solution you'd like:

Can we add instrumentation for the runtime metrics so that we can demonstrate the monitoring of these runtime environments?

Describe alternatives you've considered.

n/a

Additional Context

We are looking at demonstrating these runtime environments monitoring recently and would be happy to contribute code to the upstream opentelemetry-demo project if that makes sense.
