What changes were proposed in this pull request?
Append custom driver env to the end of spark-env.sh in driver pod to ensure precedence.
Why are the changes needed?
Within the Spark driver pod, the spark-submit script execution process sources the spark-env.sh configuration file. Environment variables defined by the user via spark.kubernetes.driverEnv.* configuration properties have the potential to be overridden by default variable definitions present in the spark-env.sh file.

No.

UT.
