I was playing around with the CLI and I noticed that the output of `bosh
public stemcells` indicates there should be a `--full` parameter; however,
it doesn't seem to work?

```
$ bosh public stemcells
...
To download use 'bosh download public stemcell <stemcell_name>'. For full
url use --full.

$ bosh download public stemcell --full
https://d26ekeud912fhb.cloudfront.net/bosh-stemcell/aws/light-bosh-stemcell-2957-aws-xen-ubuntu-trusty-go_agent.tgz
invalid option: --full
Usage: bosh download public stemcell <stemcell_filename>
```

Is the `--full` parameter deprecated?

Thanks!
