Kafka buffer integration test for backward compatibility

[graytaylor0]

Is your feature request related to a problem? Please describe.
Data Prepper does not have any backward compatibility integration tests with persistent buffer. This means that there could be code in the kafka producer and consumer that break backward compatibility (i.e. old data prepper code produces to Kafka, but new Data Prepper consumer code cannot consume the old producer's data)

Describe the solution you'd like
An integration test in the form of a github action with the following flow

1. Ingests to a pipeline and produce the data to the Kafka buffer (with kms encryption enabled) with the latest data prepper image code.
2. Pause to block consuming of the data so that the data remains in the Kafka buffer
3. Start up data prepper running the latest code in github (not the latest image)
4. Verify no failure to consume the data and that the data is consistent with what was produced in step 1.

Start up data prepper running the latest code in github (not the latest image)

We should probably do this in the Gradle build actually. Our end-to-end tests already do this for OpenSearch at least. Also, it would ideally be the latest version of the current major version. That is, using the 2 tag instead of latest.
