Title: [SPARK-2392] Executors should not start their own HTTP servers

Executors currently start their own unused HTTP file servers. This is because we use the same SparkEnv class for both executors and drivers, and we do not distinguish this case.

In the longer term, we should separate out SparkEnv for the driver and SparkEnv for the executors.
