Description
The jvm-dtests are taking long enough now to warrant moving them from the 'Test' stage to the 'Distributed Test' stage in the Jenkins pipeline.
That is, jvm-dtests is now taking significantly longer than any of the other unit test jobs in the 'Test' stage, increasing the time the time the whole pipeline takes.
Moving both jvm-dtest and jvm-dtest-upgrade to the `Distributed Test`, and splitting them (changing the job to a matrix), will reduce the pipeline runtime. Such grouping also makes sense logically.
