#12811 - compressing simple class name for observation

[bvn13]

I tried to compile the project locally in order to test it.
But unfortunately I had the error below. And I definitely don't know how to fix it.
I would try to check open-telemetry locally if you help me to compile the project.

Compress Filter Chain Observation Names

Closes gh-12811

@jzheaux Please take a look at my PR

Thanks for your help with this PR, @bvn13! I made a polish to use the simple name and adjusted the observations a bit. Also, I removed the OpenTelemetry-specific code as per our discussion.

For the time being, I'd like to wait on configuration, so I also removed the registerName method. I think that at some point we could have a setter were a set of event names could be provided or similar, but for now I'm not clear on how filter chain observation is going to evolve.

This is now merged into main; thanks again!
