Prototype sending data via VS OTel collector

[JanKrivanek]

Motivation

We want to evaluate viability and benefits of using the new VS OTel collector. Specifically this should help us sample and filter-out/in data that would otherwise be of a too high volume for us.

Goals

• Prototype sending data from MSBuild (idealy those defined in https://github.com/dotnet/msbuild/issues/10946) via VS OTel collector (doesn't need to be mergable, can be runnable just localy with manual setup)
• Experiment with and document the head filtering capability
