* Return the request dictionary in the results
It's sometimes useful to have access to the request params in a k8s
style. The dictionary returned by the request_params call can be
serialized into YAML to produce a k8s like file.
* Add dry_run option to skip module execution
By having support for dry_run executions, it'll be possible to generate
YAML files from the results dictionary by using the data in the
`requests` key.
