Run gerrit 3.2 and 3.3 functional tests

This change splits our existing system-config-run-review job into two
jobs, one for gerrit 3.2 and another for 3.3. The biggest change is that
we use a var called zuul_test_gerrit_version to select which version we
want and that ends up in the fake group file written out by Zuul for the
nested ansible run. The nested ansible run will then populate the
docker-compose file with the appropriate version for us.
