Complete description

This PR modifies the papermill plugin so that, if a kwarg render_deck is passed, the flyte deck is added automatically, without need for a follow up task. The render_deck kwarg was used to ensure backwards compatibility, by default, the behaviour of the papermill plugin won't be changed (i.e., this deck support is opt-in).

Note that this won't happen for cached execution, there is an open issue out for fixing flyte decks for cached execution.

I tested this change by installing this branch of flytekit into a container and registering one of our company's test notebook tasks, and running it. It gets a deck as intended:

Not 100% happy with how I tested this plugin. Since the unit tests use local execution, the deck/context functionality I think isn't getting used. Let me know if there is a better way to do test this.
