Open Telemetry extensions

OpenTelemetry extensions

These libraries are ment as extensions for the Open Telemetry project. They provide functionality that makes working with traces, and logs easier.

Currently, there is support for:

• http severs through otelmiddleware
• logging with zerolog, slog, logrus

More extensions might follow for other logging libraries and more.
