Fix spark-integration-test-minikube-k8s issue

1. Remove deprecated role "install-docker-ce"
2. Apply role "install-openjdk" instead of installing OpenJDK in run.yaml
3. Add option "--r" for command "make-distribution.sh" in minikube job
   to avoid following docker build error because R code can't be found
   in docker file.
