Add mechanisms for federating poll results (especially private polls)
Unless I'm mistaken, there is currently no mechanism in Pleroma to send poll results over the federation. This is an issue in particular for private polls, as only the authoring instance will be able to see the results.
Mastodon uses an Update
activity to send updates to the Question
activity to followers/voters when it gets new votes / when the poll expires. The use of such an Update
activity alleviates the need for user-authenticated fetching of the Question
object.
