Improve jar names for Data Prepper plugins

[dlvenable]

Is your feature request related to a problem? Please describe.

Data Prepper plugins have Gradle module names such as opensearch, common, kafka-plugins`, etc. These are good in Gradle. But, in the Docker image (and eventually on Maven), these names can be confusing.

In particular, I noticed this with the opensearch-2.9.0 jar file. I thought this was OpenSearch 2.9.0. This also caused vulnerability scans to detect that this had a vulnerability which is valid for OpenSearch 2.9.0, not Data Prepper's opensearch sink/source.

docker run opensearchproject/data-prepper:2.9.0 ls /usr/share/data-prepper/lib/opensearch-2.9.0.jar
/usr/share/data-prepper/lib/opensearch-2.9.0.jar

Running a jar listing reveals that this is Data Prepper's opensearch plugin.

docker run opensearchproject/data-prepper:2.9.0 jar tvf /usr/share/data-prepper/lib/opensearch-2.9.0.jar | grep Sink

Describe the solution you'd like

I'd like to rename the jar files that Data Prepper produces to start all Data Prepper plugins with data-prepper-plugin-.

At the same time, I'd like to keep the module names in Gradle the same. We can configure Gradle to change the way it produces output to help with this.
