Steve Howell fa505a1af1 refactor: Have process_success return structured data.
Before this change subclasses of OutgoingWebhookServiceInterface
would return a raw string as the first element of its return
tuple in process_success().  This is not a very flexible
design, as it prevents the bot from passing extra data like
`widget_content`.

It's also possible in the future that we'll want to let outgoing
bots reply directly to senders who mention them on streams, and
again the original design was overly constrained for that.

This commit does not actually change any functionality yet.
