* Migrate to using gradle platform to manage dependency versions instead of global variables.
* Remove unused and fix test
* Revert test yolo
* Workaround test ordering issue by just merging them
* Spot
* omit metrics artifacts (alpha) from the bill of materials (bom)
* Hack the version number for maven publications that end in -metrics.
* Remove the failed attempt.
There are some things left to be done:
* Decide if context package should also be opentelemetry-api-context.
* Cleanup internal packages, things that are used by only one artifact should be moved there.
