[SPARK-4253] Ignore spark.driver.host in yarn-cluster and standalone-cluster modes

In yarn-cluster and standalone-cluster modes, we don't know where driver will run until it is launched.  If the `spark.driver.host` property is set on the submitting machine and propagated to the driver through SparkConf then this will lead to errors when the driver launches.

This patch fixes this issue by dropping the `spark.driver.host` property in SparkSubmit when running in a cluster deploy mode.

[SPARK-4745] Fix get_existing_cluster() function with multiple security groups

The current get_existing_cluster() function would only find an instance belonged to a cluster if the instance's security groups == cluster_name + "-master" (or "-slaves"). This fix allows for multiple security groups by checking if the cluster_name + "-master" security group is in the list of groups for a particular instance.
