feat: Add tracing integration to profiling.

[cyriltovena]

What this PR does:

This adds tracing integration to pprof profiling. Every root span ID per service will be added to the profiling data using pprof labels and then forward to Pyroscope.

This allows to show flamegraph for a given trace

Which can be useful to understand resource usage per trace.

@cyriltovena I saw that you checked the Documentation added box. Did you update doc or just add the changelog entry? If the latter, we can make a doc issue to update the Tempo doc and other doc sets, as needed.

Generally looks good but I think you need to run:

make update-mod

to tidy up the serverless go.mods

I don't think this needs to be mentioned in the doc. This is why I checked that box. I think a changelog entry is enough yes.

We are getting this on other PRs too. This fix works locally, I will test it on my PR:

github.com/mattn/go-ieproxy v0.0.11 // indirect
