Continue working on instrumentation registration

Cleaned up instrumentation registration pattern, where any module can register it's own instrumentation package, by preparing a simple extension method, that would be called in the `Program.cs` to register it within the instrumentation sources. Everything handled by interfaces and extension methods.
A room for improvement using source generators in the future.
