Major version update (version 2.0.0) for OTel Java instrumentation (#1352)

* Major version update (version 2.0.0) for OTel Java instrumentation for
adservice, frauddetectionservice, kafka

The new Java instrumentation uses HTTP as the default export protocol. This PR changes the Java services to export HTTP instead of gRPC.

The new Java instrumentation introduces a lot of new kafka.consumer.* metrics from frauddetectionservice.

* Add CHANGELOG

* Fix CHANGELOG. Update docker-compose.minimal.yml
