Add version info to results

[hariso]

Feature description

When comparing different test runs, it's good to know what version of a tool/connector was used for it. Ideally, the version of both the tool and the connector that were used is provided.

The only thing we know is the container docker image, which ideally references the version. Is that what you had in mind?

For the record, the team discussed this issue and we don't think it's something that needs to be tackled now, given that we'll focus on other things in the next milestone.

As for the above question, the idea was to return the information about the connectors too, especially because in Kafka Connect they're installed separately.

I think this is essential to provide. And especially for Conduit Core - I can't find any mention of which version of that is used. Your published benchmarks apparently used 13.2 when the latest version at that time was actually 13.4 or 13.5.
