otelconf: move experimental types to otelconf/x

[codeboten]

The otelconf package now only includes the subset of features that are
stable in the configuration schema. The package otelconf/x must be used
for anyone looking to utilize experimental types.

Note to reviewers: the PR contains a lot of code, most of it is duplicated code. The Makefile genjsonschema now puts the initial generated code (including experimental features) in otelconf/x, then generated_config.go is processed by a second sed script to remove experimental features, the results of which land in the root of the otelconf package.

Is there any way to see the parts that are new compared to the base otelconf? Or at least a way to search for them so I can pay more attention there

The changes in otelconf in this PR are all subtractions, you can look at the resulting diff. Or is what you're asking if there's a way to see the diff between otelconf and otelconf/x moving forward?

[dashpole]

I see. So all of the added lines of code are a copy without modification (besides being in a new module).

[dashpole]

Is this leftover from when you generated the /x package, or is this something that we are going to use going forward to manage the differences between otelconf and otelconf/x?

[codeboten]

This will be used moving forward, it works for now, open to suggestions to improve the flow here
