cmd/trace: execution tracer is essentially not documented

[AlekSi]

I was able to find only 3 short mentions:

• Command trace
• Package trace
• Go 1.5 changelog

They are not very helpful. Compare this to how race detector (article, blog post) or pprof (blog post) is documented. People on Reddit even think that trace tool flopped.
#11605 mentions future blog post, but it never materialised.

Execution tracer just got some documentation… in the form of this talk.

There is an external package with some documentation for events format: go-trace.

This article by Pusher.com (2017) is nice.

If it helps, I did write this long time ago: https://github.com/campoy/go-tooling-workshop/blob/master/3-dynamic-analysis/4-tracing/1-tracing.md
