Add tracing information to all components

[codeboten]

Now that it is possible to emit traces from the Collector, it would be great produce spans consistently across components. This issue is a general issue that will include a checklist for all components in this repo.

Describe the solution you'd like
Each component produces a span using the StartTracesOp and EndTracesOp methods available in obsreport.

What needs to be done? Any hints? I would love to contribute.

I still like the solution that implemented it in consumer so it automatically happened everywhere: #8833

I'll take a look and try to send a PR. Thanks @TylerHelmuth

I would be concern to add traces for each individual component. Think about a simple processor that would not benefit.
