Add http request metrics to either http or express package

[icco]

Is your feature request related to a problem? Please describe

While I can figure out RPS from traces, if traces are sampled, this number is wrong.

Describe the solution you'd like to see

I would like to see the metrics described in https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/metrics/semantic_conventions/http-metrics.md exported by one of these two libraries.

Describe alternatives you've considered

Additional context

The newly released http instrumentation should allow you to do this: #3149

[icco]

Oh that's cool. We have that version but haven't seen those metrics yet. I also would like the rest of the metrics in the spec implemented:

Liked metrics will all be added to http instrumentation, rather than express. I'll move this issue there, @icco.

[legendecas]

The necessary change has been released in @opentelemetry/instrumentation-http v0.33.0. I'm closing this as completed.

[icco]

Just to be clear @legendecas, that change only adds http.client.duration and http.response.duration, the rest of the metrics are still missing.

[icco]

I will try and put together a PR to add those metrics.
