What changes were proposed in this pull request?
Currently, spark on kubernetes can't show logs url on ui. To check history logs, we usually collect pod logs to third-party logging services, which can be accessed by urls. To show log urls on ui, we can set env prefixed with 'SPARK_LOG_URL_' for executors. But for driver, there is no way to show log urls by setting env.
This pr use 'SPARK_DRIVER_LOG_URL_' as env prefix for getting driver log urls by default.
Why are the changes needed?

Does this PR introduce any user-facing change?
