Introduce four new command line arguments to spark-submit: ``` --yarn-docker-image --yarn-docker-mounts --executor-docker-image --executor-docker-mounts ``` Together, they can hide the boilerplate for using Docker on YARN: ```sh --conf spark.yarn.appMasterEnv.YARN_CONTAINER_RUNTIME_TYPE=docker --conf spark.yarn.appMasterEnv.YARN_CONTAINER_RUNTIME_DOCKER_IMAGE=repo/image:tag --conf spark.yarn.appMasterEnv.YARN_CONTAINER_RUNTIME_DOCKER_MOUNTS="/etc/passwd:/etc/passwd:ro,/etc/hadoop:/etc/hadoop:ro" --conf spark.executorEnv.YARN_CONTAINER_RUNTIME_TYPE=docker --conf spark.executorEnv.YARN_CONTAINER_RUNTIME_DOCKER_IMAGE=repo/image:tag --conf spark.executorEnv.YARN_CONTAINER_RUNTIME_DOCKER_MOUNTS="/etc/passwd:/etc/passwd:ro,/etc/hadoop:/etc/hadoop:ro" ``` Signed-off-by: Anne Macedo <annie@retpolanne.com>

Does this PR introduce any user-facing change?
It adds the aforementioned command line arguments, that will be available on
spark-submitand subsequentlyspark-shellonce this PR is applied.How was this patch tested?
Tests were added, where it is tested if the configs from the boilerplace are properly applied. It was also tested using Github actions.
To do: test these changes on a real YARN cluster.
