Change looks largely fine. With this addition of this and ES_6.8 how many combinations will we have? I'm wondering if we want to hold off on adding these to the Jenkins matrix until we add support for running multiple combinations on one worker, say with some minor edits to the test_runner.py to support say running all target combos for a given source version

I have disabled the Matrix pipeline on jenkins for this newly added target OS_3.1. For testing purposes, we can leverage the k8s-local-integ-test pipeline by building with parameters.
