Should OData libraries expose telemetry data?

[habbes]

Hi all. There's been people asking whether OData libraries could be instrumented to provide telemetry data. We're considering adding this instrumentation and wanted to know whether this is something more people would find valuable, and if so what kind of data (spans, events, metrics, etc.) they would like to get from this.

Some initial thoughts are to start with basic data in the core library like:

• spans that track when writing a payload starts and ends
• exception and validation error events

The application developer using OData libraries can consume this telemetry using OpenTelemetry libraries, tools and send them to their application performance monitoring tools.
