Set spark.driver.host to localhost in integration tests

[teamurko]

Summary

Started getting binding failure because hostname has changed from 127.0.0.1 to some internal network ip. spark.driver.bindAddress defaults to {spark.driver.host}. It's a common practice to set driver host to localhost in tests.

Can't assign requested address: Service 'sparkDriver' failed after 16 retries (on a random free port)! Consider explicitly setting the appropriate binding address for the service 'sparkDriver' (for example spark.driver.bindAddress for SparkDriver) to the correct binding address.
