* Move OpenTelemetry SDK out of bootstrap loader
* Improve shading
After this change, the shaded opentelemetry-sdk is only used by test
modules, so it doesn't need to be published.
* Move things up a directory
* Scripted mass update
find -type f -name "*.gradle" | xargs sed -i 's/:java-agent:/:/g'
* Remove plugin version now that it's in root module
* Update java-agent and instrumentation configs
* Misc
