1. Add a OpenTelemetry-like shim-layer to collect traces 2. Add a simple builtin trace collector and exporter, end users could download the diagnosis report to get the traces. This PR's design is quite lightweight, no hard-dependency, and it is easy to improve or remove. We can try it on gitea.com first to see whether it works well, and fine tune the details. --------- Co-authored-by: silverwind <me@silverwind.io>
