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
```
