SPARK-2333 - spark_ec2 script should allow option for existing security group
- Uses the name tag to identify machines in a cluster.
- Allows overriding the security group name so it doesn't need to coincide with the cluster name.
- Outputs the request id's of up to 10 pending spot instance requests.
