The Spark UI is started by default on port 4040 (with retries on conflict) for every SparkSession created in the test suites. It serves no purpose during automated testing, consumes resources, and is a common source of port-binding noise when tests run in parallel. Disable it in the two places that build test SparkSessions: - SparkTestUtils.defaultSparkConf (used by all integration tests, including SharedClusterSparkIntegrationTestBase and CoordinatedBulkWriteSimpleTest) - TestUtils.Holder#createSession (the shared unit-test SparkSession in cassandra-analytics-core) Patch by Tejas Lodaya for CASSANALYTICS-67
