[SPARK-5628] Add version option to spark-ec2
Every proper command line tool should include a `--version` option or something similar.
This PR adds this to `spark-ec2` using the standard functionality provided by `optparse`.
One thing we don't do here is follow the Python convention of setting `__version__`, since it seems awkward given how `spark-ec2` is laid out.
