[SPARK-24232][K8S] Add support for secret env vars

## What changes were proposed in this pull request? * Allows to refer a secret as an env var. * Introduces new config properties in the form: spark.kubernetes{driver,executor}.secretKeyRef.ENV_NAME=name:key ENV_NAME is case sensitive. * Updates docs. * Adds required unit tests. ## How was this patch tested? Manually tested and confirmed that the secrets exist in driver's and executor's container env. Also job finished successfully. First created a secret with the following yaml: ``` apiVersion: v1 kind: Secret metadata: name: test-secret data: username: c3RhdnJvcwo= password: Mzk1MjgkdmRnN0pi ------- $ echo -n 'stavros' | base64 c3RhdnJvcw== $ echo -n '39528$vdg7Jb' | base64 MWYyZDFlMmU2N2Rm ``` Run a job as follows: ```./bin/spark-submit \ --master k8s://http://localhost:9000 \ --deploy-mode cluster \ --name spark-pi \ --class org.apache.spark.examples.SparkPi \ --conf spark.executor.instances=1 \ --conf spark.kubernetes.container.image=skonto/spark:k8envs3 \ --conf spark.kubernetes.driver.secretKeyRef.MY_USERNAME=test-secret:username \ --conf spark.kubernetes.driver.secretKeyRef.My_password=test-secret:password \ --conf spark.kubernetes.executor.secretKeyRef.MY_USERNAME=test-secret:username \ --conf spark.kubernetes.executor.secretKeyRef.My_password=test-secret:password \ local:///opt/spark/examples/jars/spark-examples_2.11-2.4.0-SNAPSHOT.jar 10000 ``` Secret loaded correctly at the driver container: ![image](https://user-images.githubusercontent.com/7945591/40174346-7fee70c8-59dd-11e8-8705-995a5472716f.png) Also if I log into the exec container: kubectl exec -it spark-pi-1526555613156-exec-1 bash bash-4.4# env > SPARK_EXECUTOR_MEMORY=1g > SPARK_EXECUTOR_CORES=1 > LANG=C.UTF-8 > HOSTNAME=spark-pi-1526555613156-exec-1 > SPARK_APPLICATION_ID=spark-application-1526555618626 > **MY_USERNAME=stavros** > > JAVA_HOME=/usr/lib/jvm/java-1.8-openjdk > KUBERNETES_PORT_443_TCP_PROTO=tcp > KUBERNETES_PORT_443_TCP_ADDR=10.100.0.1 > JAVA_VERSION=8u151 > KUBERNETES_PORT=tcp://10.100.0.1:443 > PWD=/opt/spark/work-dir > HOME=/root > SPARK_LOCAL_DIRS=/var/data/spark-b569b0ae-b7ef-4f91-bcd5-0f55535d3564 > KUBERNETES_SERVICE_PORT_HTTPS=443 > KUBERNETES_PORT_443_TCP_PORT=443 > SPARK_HOME=/opt/spark > SPARK_DRIVER_URL=spark://CoarseGrainedSchedulerspark-pi-1526555613156-driver-svc.default.svc:7078 > KUBERNETES_PORT_443_TCP=tcp://10.100.0.1:443 > SPARK_EXECUTOR_POD_IP=9.0.9.77 > TERM=xterm > SPARK_EXECUTOR_ID=1 > SHLVL=1 > KUBERNETES_SERVICE_PORT=443 > SPARK_CONF_DIR=/opt/spark/conf > PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/lib/jvm/java-1.8-openjdk/jre/bin:/usr/lib/jvm/java-1.8-openjdk/bin > JAVA_ALPINE_VERSION=8.151.12-r0 > KUBERNETES_SERVICE_HOST=10.100.0.1 > **My_password=39528$vdg7Jb** > _=/usr/bin/env > Author: Stavros Kontopoulos <stavros.kontopoulos@lightbend.com> Closes #21317 from skonto/k8s-fix-env-secrets.
