SPARK-1450 [EC2] Specify the default zone in the EC2 script help
This looks like a one-liner, so I took a shot at it. There can be no fixed default availability zone since the names are different per region. But the default behavior can be documented:
```
if opts.zone == "":
opts.zone = random.choice(conn.get_all_zones()).name
```

Closes #3454 from srowen/SPARK-1450 and squashes the following commits:
9193cf3 [Sean Owen] Document that --zone defaults to a single random zone
