Have submitted a PR.  Apologies if light on content, but it's my first contribution to Airflow.

> The S3KeySensor doesn't currently return useful information about the key that was recognised if doing a wildcard lookup.
> My proposal is to modify the S3KeySensor, so that if a key exists, it'll then list the keys that are matched in the S3Bucket using hook.list_keys() - and then publish these to xcom.
